In the front part of green dot laser alignment, laser tech professionals have specially designed adjustable focus design. According to simple and easy screw of heat part, users can easily obtain different size of green dot on required working surfaces. Laser engineers have made test with a 5mW green dot laser alignment at 1 meter working distance. The targeting green dot can be controlled at 1mm to 2mm. With the increasing of selecting output power, the size of green dot becomes bigger and bigger. Usually the acceptable working distance should not exceed 20 meters. At 20 meters working distance, the green dot size can reach as big as 8mm to 10mm. On condition that users are requiring especially strict dot measurement, users should make strict selection of output power and working distance of green laser alignment tool during dot generation work.
In practical dot projecting working fields, users can easily mount green dot laser alignment on vertical or horizontal surfaces of required machine or devices. The specially used mounting bracket also users to make easy installation and adjustment of alignment laser tool until getting the best dot targeting direction in operation. After suitable selection of output power, easy mounting and installation, this dot projecting alignment laser tool can just bring workers the most satisfied dot projection on all working surfaces efficiently.
