In various precise and fine line alignment at various work distances, unless the use of sunlight, it is making the best job to operate Berlinlasers 532nm green laser line generator. It projects the most visible green laser light and the lowest laser beam divergence of less than 1mrad. Besides its operation of close distance, high power laser device up to 50mW to 100mW makes good job for clear line indication at great distance and high lighting.
This green line laser module is applying the most qualified separate crystal lens, it gets the best laser light source than formal glass or plastic coated lens. Under operation of highly uniform green line emission, it is also keeping the same line brightness from middle part towards both ends. It makes good job for no mistake measurement for laser cutting, sand milling, lumber machine, textile garment processing and high tech work etc.
