how can dc power berlinlasers 5mw to 100mw red laser line generator work correctly?

unlike the use of prior line drawing work, on consideration of high work efficiency and high fineness, it should be a good solution to use berlinlasers 5mw to 100mw 650nm red laser line generator. the adoption of a metal heat sink is cooperating with high duration metal housing tube, it enables increasing stability red laser beam and red line projection from beam aperture effectively.
the advanced use of a qualified glass coated lens and glass lens are cooperating well, this laser line generator gets different line lengths and line fineness at different work distances. it gets specially designed adjustable focus optic lens, after immediate red laser light source concentration, it brings users increasing accuracy and brightness line generation at great distance and formal lighting occasions constantly.
applications: guideline for laser cutting, textile garment processing, lumber machine, laser car wheel alignment and high tech etc
