When line measuring work is processing with Berlinlasers 100mW green laser line generator, after quite easy use of external DC input power supply, it keeps work with continuous green laser beam emission and highly clear green line projection in distance. It is being made with 26mm diameter aluminum alloy housing tube, equipping with inner metal heat sink cooling system and APC, ACC driving circuit board, it assures superior nice thermal conductivity and increasing stability green line projection in continuous use. Owing to quite special use of glass coated lens or separate crystal lens, within 10 to 110 degree fan angles, 100mW green laser line generator is projecting extremely fine and straight green line onto various targeting surfaces. It keeps work with high linear quality and highly fine green line projection, without any appearance of laser light decay or blur in continuous use. This green laser module should be selecting with correct optic lens. When it is installing onto industrial machine or device, after quite easy adjustment of laser beam focus and laser line targeting direction, it achieves high precision line measurement in distance perfectly.
