Owing to the use of short wavelength of 405nm, the real use of a violet laser diode module always gets a bit bright violet laser light source than UV lasers and high energy generation. It is able to achieve high precision processing and detection. Owing to its low beam divergence angle and special adjustable focus optic lens design, it concentrate higher energy in a small area, which is workable for applications that require high energy and ultra compact size violet dot projection in distance. 
This laser diode module applies a qualified glass coated lens and import laser diode inside the durable metal housing tube, it ensures good collimation violet laser light emission, and converts into highly clear and bright violet dot projection onto multiple raw material surfaces. Owing to its superior nice thermal emitting and thermal stabilization performance, it enables long time lasting violet dot projection and long serving lifetime in all industrial and high tech precision alignment works effectively.
Applications: industrial visual detection, laser engraving, laser cutting, exciting of fluorescence, scientific experiment
