The Technology behind Golf Rangefinder

Optical technology is the key to an effective rangefinder to be used for golf sports. The pulses emitted by the targets in your view range are captured by the device lens. The optical design of the transmitting channels captures these pulses and converts them into images. The eyepiece of the device helps you view these images clearly. This is said to be only the basic part of what you get to view.

Splitting this process further you get into the detailing part. Here you come across many minute aspects like horizontal distance calculations, sloping angle measurement, flag indicator images, distance to the nearest pin, between pole distances etc.

Rangefinder Lens parameters

· The resolution factor of the golf rangefinder helps in differentiating between two or more different objects which are located in the same horizontal plane. For example a hole and a hazard might be located in the same plane. The swing angle you take and the force you apply can make the ball land near the hole or into the hazard. A good rangefinder is supposed to help you in calculating the distance between you and the target and the hazard as well as the distance between the target and the hazard. This could help you in calculating the most optimum swing angle and force.

· Multiple Targets can be set in sequence of execution with the rangefinder. This is said to be made possible by the marking and storing feature. This could help you to start scoring your shots from the targets which are closest to you and then move along by incrementing the range of distances.

· Actual view of the field and the image view in the rangefinder could vary slightly depending on the magnification factor. This could create an illusion that the object is nearer or further to you than the actual distance. This is when you end up making miscalculations on the swing. A good golf rangefinder is supposed to resolve this issue by self adjusting the magnification factor with the focal distance to give you the actual view of the field and the objects in it.

· Measurement response time is said to be very vital in determining the quickness with which you mark the targets and start striking. Professional rangefinders are known to for a response time ranging from 0.5 seconds and less. If you are able to find a device which can dynamically vary this parameter depending on the speed with which you change your view you could say that’s a good one you can opt for.

· Range of view is something the professional golfers need to be clear about. The width and length of the filed coverage by the rangefinder can help you in calculating the distance between multiple objects in the range. A good rangefinder is said to give you accuracy in short distance coverage as well as long distance coverage. It helps in resolving the distance between you current location and the multiple objects by displaying the distance and angle of object location. It can also show you the inter object distances and angles.

· Multiple mode of view is an essential feature which allows you to switch between horizontal and slope views dynamically. Auto adjustment of distance calculations in the sloping angles gives you the option of choosing the right kind of golf club for playing accurate “uphill” shots.

· Uphill distance display is a feature which calculates the actual distance between you and the hole located at a vertical height and distance away from your current location. This will help you choose the right shot trajectory that makes the ball land very close to the target or into it, depending on the need. The same logic can be applied to the “downhill” target. The only difference is the angle of elevation and the angle of declination. Standard golf rangers are said to be capable of gauging the actual distance by a formula based on the geometrical resolution of the virtual “triangle” between you, the elevated target and the horizontal distance between you and the base of the elevated target. This is supposed to give you the accurate angle of elevation and the actual distance in the slope.

· Object diameter /dimension measurement is a feature which can help you in calculating the swing parameters accurately. This varies between targets in the plain and those at angular distances. A good rangefinder is supposed to give you near accurate values across elevated and horizontal distances for short and long distances.

Rangefinder Eyepiece Parameters

· Eye relief is a feature which can help in relieving the stress on your eyes while you are in continual viewing mode. This depends on the way in which the eyepiece is designed. A good rangefinder is supposed to adjust the display intensity according to the varying light and shadow in the surrounding environment.

· Refractive Index of the view could vary when you use the rangefinder without spectacles and by wearing them. Professional rangefinders are supposed to be capable of displaying the angles and inclination and declination as well as horizontal views accurately without any variations for spectacled view and normal view.

Device parameters

· Temperature tolerance is a feature of the device allows you to use it in multiple climatic conditions without affecting the display resolution. You need to find out about the range of temperature tolerance (+/-) while choosing the best golf rangefinder for your needs.

· Dimension and Weight of the device is important feature which determines the ease of carrying and using it. You are recommended to select the device which is optimally light in weight and compact in size. At the same time you are suggested to take care of the optical device dimensions which need to have minimum values.

Some of the products which you might find with these features are listed here.

current-price-CTA-300x33

Component Design and Assembly

Compact Binoculars

Modern binocular design seems to be based on enhancing the attributes of components by reducing their dimensions. Components are categorized into critical, essential and feature enhancing groups.

Critical components are said to be the lenses, prism, eyepiece, external casing etc. Essential components are said to be the image intensifier tubes, lens housing, infrared illuminator, protective armors, surface panels, chassis, adjustment knobs etc.

The feature enhancing components are said to be the eye cups, focus lock, exit pupil, lens protectors, tripods and so on. In addition the binoculars could have coating elements, purging agents, polishing and finishing compounds etc for enhancing the quality and functionality of the components.

Critical Component Features

Objective lenses

  • Focal point fixing is one of the main functions of the objective lens. This is done by capturing the target object image from short and long range distances. The light reflected by the object passes through the two lenses into the barrel and reaches the eyepiece. The objective lens performs many functions on this light before letting it through.
  • Magnification is the next function of the objective lens. This depends on the stated capacity by the manufacturer. Resolution of the object image refers to the pixel density. This can be enhanced by field flattening, image stabilization and by overcoming hand tremors and image aberration.
  • Enhancing the Apparent field of view by multiplying the real field of view with magnification factor is said to be one of the typical characteristics of the objective lens. A good objective lens can perform this function effectively, regardless of the distance at which the target object is located. Of course there is a limitation to which it can work, which increases with the lens quality.
  • Image circle fixing is one of the important aspects of the objective lens. This is said to be taken care of by the lens aperture. According to optic experts this value should be preferably high as it influences the aperture of the exit pupil which is obtained by dividing this value by the magnification factor.
  • Twilight feature is to enable viewing of clear and bright images during and after sunset time (before darkness). This can be enhanced with the increase of objective lens aperture and the magnification factor.
  • Image quality is enhanced by absorbing maximum light from the target object by avoiding reverse reflections around the lens peripherals. This is said to be achieved with the help of anti reflective lens coating. Dielectric materials are said to be useful for multi coating of the objective lens.
  • Benefits of anti reflective coating are said to be maximum light absorption, proper routing of light rays, oxygen repulsion; transmission efficiency and dispersion reduction. Hydrophobic materials are commonly used for lens coating.
  • Error reducing factors refer to blurriness, chromatic aberration, discoloration, distortion excess contrast and filed curvature. This is said to be achieved by passing the lenses through proper processing techniques to correct optical parameters.

When you go through the detailed technical specifications related to the optimum values for these factors you will be able to make a better decision while choosing the compact binocular.

Binocular Prism

  • Angle varying prism and erecting prism are said to be the two basic versions used in a good quality binocular. Angle varying prism is said to play an important role in adjusting the refraction angle of light. Erecting prism is said to be useful for making corrections to the inverted images.
  • Types of prism commonly used in binocular are said to be Porro and roof. In Porro type of prism the light goes through Z path while in roof prism the light passes through a straight line, which is said to be preferred for compact binocular.
  • Prism coating is said to be commonly done with silver, aluminum, HR and dielectric materials etc. This is done in multiple layers to enable maximum reflections of the light, resulting in brighter images.
  • BAK4 and BK7 are the two commonly used grades of glass used in the prism. BAK4 is said to be barium based while BK7 is boron based. Level of transparency is said to be relatively more in BAK4 which can result in brighter images. This could be due to the fact that the distance traversed by the light is shorter, resulting in lesser absorption.
  • Important prism parameters which determine its quality are said to be close focus, eye relief, field of view, magnification, image error reduction, image sharpening and image focusing capabilities. It could be tough to find all the features in one prism alone, hence you might choose the right sort of parameter based on your need based on the model of compact binocular you select.

Binocular Eyepiece

Most of the characteristics of the eyepiece lens are said to be based on the error correcting features of the objective lens and the prism.

Aspherical type of lens is said to be common type used here. This lens is also multicoated to reduce internal glare to maximum possible extent.

Eyepiece lens can be moved by rotating the eyepiece casing while objective lens are said to be relatively static in nature.

External Casing

Metals and alloys like magnesium, brass, zinc, copper, aluminum and many other stress proof materials are commonly used for constructing the external casing of the compact binoculars.

Some of the latest versions might also use polycarbonate and other polymer fusions to keep the device lightweight and easy to handle.

Essential Binocular Components

  • Intensifier tubes are said to be useful for controlling the brightness of light with the help of adjusting knobs.
  • Lens housing is supposed to be used for giving protection to the lens. In case of eyepiece lens the housing also enables rotation of the lens to a limited extent for varying the angles of focus.
  • Infrared illuminator is aid to be used for increasing the image sharpness during twilight hours and cloudy or foggy weather conditions.
  • Protective armor is said to be useful for safeguarding the complete binocular from water, fog, dust and other external elements. O-ring is another protective lock which can help in protecting the device from heat, wind and water.

While selecting the compact binocular for your usage, you could checkout with the component features listed above to ensure that you get the best quality device.

Technical and Functional Features of the Hunting Binocular

The key to a good hunting binocular is the technology on which it works. This gets reflected in its design and architecture as the basic forms. Once you understand these two, the way you interpret the functional features becomes lot easier.

Hunter with Animal

Design of the Hunting Binocular

The design of the hunting binocular is about the way in which external casing and its dimension, the twin barrels, focus wheel, lenses, the eyepiece, prism and other parts are assembled in line with each other. The basic design of a binocular remains more or less the same across all models.

• External casing is mostly made of metal like magnesium or combination of engineering plastic like polycarbonate. The external surfaces of the binocular are usually coated with rust and water proof metallic alloy.

• The twin barrels of binocular are positioned with the adjustable eyepiece collars. The level of adjustment is said to determine the quality of image and the ease of viewing.

The design of the eye cup determines the comfort level of viewing with or without wearing eyeglasses.

The barrel and inner tube diameter specifications determine the diameter of the objective lens, prism dimensions and the diameter of eyepiece lens.

• The construction of the binoculars external casing and internal layers need to be done in a way to prevent accumulation of moisture, dust, mold and other contaminants from the external environment.

Assembling parts like the screws, rings and other supporting parts need to be strongly fastened with the main parts, at the same allow easy movements.

• All the optical parts need to be protected from external elements like heat, wind, mold, dust and other contaminants, while allowing sufficient space for light to enter through multiple angles from the reflecting target object and the rest of external world.

You need to take care of all these features while choosing the binocular for hunting purpose.

Optics of the Hunting Binocular

The construction of the optical parts determines the functional efficiency of the entire binocular.

Diameter and aperture of the objective lens determine the focal ratio, aberration, dispersion, focal length, range of coverage and other image sensing parameters. Lens curvature could vary among different models of binoculars with the same objective lens diameter. This difference is said to be due to the ways in which the finishing is done on them.

• Aperture size is said to play an important role in determining the clarity of image and reduction in the errors of focus and view. Some of the most commonly found errors in the hunting binocular are related to quality (chromatic, spherical, coma and astigmatism) and position (field of curvature and distortion).

One way of improving the quality of optics parameters is said to be reduction of error percentage in the glass parts. This is mentioned by most of the optic experts, probably due to the reason that errors could be an inherent part of glass parts of any optical device due to unavoidable factors during manufacturing, finishing and assembly.

Optical Quality Improvement

• Chromatic aberration needs to be reduced in order to improve the refractive index of the binocular. This is said to reduce the dispersion of light as it passes though the objective lens and the prism. Most prominent optical parts to have chromatic aberration are said to be the objective lens and the eyepiece. According to optic experts this error could only be reduced but not necessarily be eliminated in any sort of binocular (with the present optic technology). One way of reducing this error is said to be by using additional lenses which could be called as doublet and triplet. By changing the glass type of fluorite type is also said to reduce the chromatic aberration considerably.

• Astigmatism is supposed to be an error in the image quality. The refracting surface of the lenses in different planes is said to cause variations in the focal length of the light across these planes. One way of reducing this error is supposed to be by keeping the aperture and the field angle at optimum level.

• Field curvature is an error in obtaining a flat image of the target object. This error could be reduced by changing the binocular design.

Distortion is an error in the sharpness of the target object image (blurriness) which is said to be common for both convex and concave types of lenses. The error in the objective lens of the binocular is said to be corrected by making adjustments in the eyepiece lens and not necessarily by correcting the objective lens alone.

Importance of Discussion about Design and Functional Features

When you have read through the design and functional parameters as well as the corrective measures to reduce the errors, you could probably have a question “Why do I need to read all these?” The reason is obvious. You might get an idea about the parameters to observe while making your selection of the best binocular for hunting.
