The usual use of an import 405nm violet laser diode and a qualified glass coated lens are configured into a durable structure made device of a violet laser diode module. It is in need to make long period extended dot alignment work, thus it gets special use of a metal heat sink cooling system and APC ACC driving circuit board inside a different dimension housing tube, which enables superior nice heat dissipation, good environmental stabilization and long operating lifetime during continuous operation.
This violet laser diode module applies a short wavelength of 405nm among visible optical spectrum, which gets low laser beam divergence and good wavelength stability. When it makes correct use of output power and operating voltage DC power supply, it can be used for laser marking on some plastics, resins, and other materials, using a high energy density violet laser beam to create a clear violet dot mark on the material surface. Violet dot laser can also be used for photocuring. The 405nm wavelength can cure certain photosensitive resins, finding applications in 3D printing and other fields.
