Technical and Functional Features of the Monocular Rangefinder

Design Parameters

· The principal parts of the device are said to be the object lens, receiving lens, LASER emitter, eyepiece and the protective body along with the battery and sockets. The effective ways in which they can be designed determine the efficiency of the rangefinder. For the most optimum design the three lenses are to be placed along the single line of assembly. This could be horizontal or vertical. The LASER emitting lens is preferably placed at the center so as to enable the reflected waves to be captured equally by the other two lenses.

· A goof monocular rangefinder has three distinct features related to optics, range finding and measuring and speed detection. The third feature is said to be responsible for the accurate detection and viewing of moving objects.

· The volume of light reflected by the target object determines its clarity of image in the eyepiece of the device. A good rangefinder is supposed to be capable of emitting LASER with a concentration level which covers all possible dimensional objects at short and long ranges.

· Normally the dark objects at long range distances are tough to be detected and viewed by the human eyes. The resolution of the rangefinder can help in overcoming this limitation. A good rangefinder is said to be capable of capturing the images of all such objects through effective mode selection. Ready to measure, continuous scan and data recall are some of the standard modes supported in general by many rangefinders of professional grade.

· Amplification of the optic system within the object lens and the receiving is said to be responsible for the targeting and viewing functions. This feature could be capable of enhancing the scanning of objects during low light time. This is also said to be responsible for the object magnification to the most optimum levels.

· Target Reflection capturing is an essential feature of the monocular rangefinder. Standard quality devices are said to be capable of capturing the least possible reflections under fading lights also. This feature is said to be enhanced by the combination of the lenses and the prism used in the rangefinder. When the light from the target object enters the receiver lens, it gets enhanced in strength depending on the quality of the device.

· Reduced light reflection is a feature which enables the device in absorbing the maximum possible light from the target objects. This could be enabled by painting the lens with a coat of non reflective material which is also highly transparent in nature. This helps in avoiding blurring of images and enhances their clarity for rangefinder and viewer parts of the device. You need to make sure that the light contrasting features of the device are kept at the lowest possible values in order to keep the light reflections near to zero levels.

· Object lens assembly design needs to be compatible for low dispersion and colour correction. This is an essential feature since the aperture size of the lens cannot be varying on either side far away from inter-papillary distance of the viewer (you). Moreover the aberration and other probable distortion factors also need to be reduced to the minimum possible levels.

· Reduction of errors in field curvature, coma, chromatic and spherical aberration are said to be enabled in a good monocular rangefinder by the alignment of lens with the prism and eyepiece. According to optics experts these features can be reduced from the system but not eliminated. Hence you need to select a monocular rangefinder device which has minimum possible error values.

Functional Features of Monocular Rangefinder

Many users often complain that their device seems to be “not so perfect” in spite of spending time and money to search and buy what they think is the best. This could be due to the practical reasons that reduction of errors in the optical devices like the monocular rangefinder, it is possible to enhance the good qualities.

· Chromatic aberration is reduced by the selection of achromatic type of lens. This is said to be capable of bringing two or more colors from the incoming light into a single point of focus. Semi apochromatic types of lens which can also reduce the value of chromatic error to great extent.

· By reducing the coma error (poor quality), the quality of the rangefinder device can be automatically improved. This is said to be made possible by the combination of two opposite comas within the same lens with embedding. Keeping the field angle and the aperture of the lens at optimum levels is another way in which it is possible to increase the quality of the rangefinder device lens.

· The refracting surfaces within the lens and the prism can have their impact on the intensity of light passing through them. As the angle of refraction increases it is possible to increase the intensity of incoming light by the convergence of multiple focal planes into a single point. This is one way in which the quality of image for monocular as well as rangefinder functionalities of the device can be improved.

· Air transparency is a factor which can affect the image quality to a critical extent. Natural elements like fog, smoke, rain and other factors can reduce the transparency of air. This can be compensated by enhancing the strength of LASER emitting lens and absorption power of the receiving lens. Optic experts recommend the usage of DAK4 or Dk7 types of prism along with multiple coated lenses in order to increase the power of receiving lens and object lens.

· Software Installation in the device is one more way in which the reflected waves from the target object can be strengthened. This feature is said to be helpful in reducing the effect of natural elements like fog, smoke, rain and other factors. This is also said to be capable of solving the problems associated with focusing on large size objects in the shorter range and smaller size objects in the longer range.
