These green laser modules are supplied in a 12mm, 16mm or 18mm heatsink case with fully enclosed built-in driver.
5mW, 10mW, 30mW and 50mW Green Laser Modules factory-fitted with a line or cross generator diffraction disc to project a green line onto a surface. New 520nm direct diode modules for harsh conditions with wide operating temperature range.
These modules have an APC (automatic power control) circuit which uses a photodiode to regulate the output, 3-5mW, 8-10mW and 10-15mW.
