If users are trying to make highly clear dot measurement for all night version fields, it is not easy to reach with any visible laser device, but substituting by a long wavelength device, such as a Berlinlasers 980nm ... dot laser alignment within 100mW to 500mW. It projects intense and powerful infrared laser light directly from a 980nm infrared laser diode. Only after equipment with night version device and constant power source supply, it keeps work with high quality IR laser light source emission and efficient conversion of highly clear IR dot emission in distance.
Being made with a qualified glass coated lens and special use of 16mm and 26mm diameter anodized aluminum alloy housing tube, 980nm infrared laser diode module enables highly stable and clear IR dot emission in distance, without any effect by harsh occasion etc. After its correct use of output power and proper adjustment of both laser beam focus and infrared dot projecting direction, it gets concentrated infrared laser light, and increasing accuracy IR dot alignment for all night version fields effectively.
