Not as bright as other visible laser devices, the general use of a 405nm violet laser diode module always projects quite charming and attractive color violet laser light from beam aperture. It is always not simply used for industrial precised to positioning work, but mainly used for special high tech fields. Being made with a short wavelength of 405nm violet laser diode, it enables high energy violet laser light emission, precise violet dot positioning. Owing to its ultra compact size and durable metal housing tube, after easy connects with DC power supply, this violet dot laser alignment enables easy installation or integration, which has become a core laser light source for biomedicine, precision manufacturing, information storage, and scientific instruments, especially irreplaceable in fluorescence excitation and precise positioning scenarios.
Basically 405nm violet laser diode module applies an import 405nm violet laser diode as its beam emitting source, available with wide range output power of 50mW to 100mW and higher power range of 150mW to 500mW. It gets specially designed cooling system in type of an inner metal heat sink for lower power range, and separate metal heat sink cooling system for higher power up to 500mW. Whenever violet dot laser alignment gets sufficient space leaving for tube heat dissipation, it can easily get ultra stable violet laser light emission, highly clear and precise violet reference dot projection for multiple precise dot positioning and alignment works. 
For the most important of all, this glass coated lens made violet laser diode module gets special use of an adjustable focus optic lens. Whenever it gets immediate violet light projection, it is easily converted into an increasing brightness and precise violet reference dot in distance. For the most important of all, being made with APC, ACC driving circuit board, whatever output power it is selected, violet alignment laser keeps work with constant violet light and violet dot projection, and long serving lifetime of more than 8,000 hours. It always perfect protection of itself from overheating and over current, and applicable for multiple industrial and high tech dot positioning works conveniently.
