When users are trying to make easy and quick line alignment at close distance, manual line drawing is far more enough to get ideal line alignment as expected. The special use of Berlinlasers 635nm 5mW red line laser module is always making easy and clear line alignment after its connect with a DC input power supply. Accepting wide range electric current within 100V to 240V, after correct use of 5V 1000mA DC power, it is generating continuous red laser beam and highly clear red reference line projection in close distance. This 635nm 5mW red line laser module selects qualified optic lens. Either it is adopting glass coated lens or separate, it is always getting quite strict laser beam stability and up to 24 hours aging prevent tests. In continuous red laser line projection, it keeps high transmittance red laser light emission and highly clear red laser line alignment in formal lighting occasions. Users should install compact structure laser line generator onto any industrial machine or device, after quite easy adjustment of laser beam focus and laser line targeting direction, it makes easy and no mistake measurement continuously.
