12X40mm green laser module adjustable focus 520nm 1mW laser module

  • adjustable focus 520nm laser module
  • 520nm 1mW laser module customized
  • 12X40mm green laser module

  • Compact Φ12×40mm true green laser diode module with 520nm wavelength and ≤1mW output (Class II), featuring an adjustable focus collimating glass lens and built-in APC constant current driver. 

    Unlike 532nm DPSS modules, this direct-injection 520nm diode starts instantly with lower power consumption and no warm-up time.

     It projects a crisp, highly visible green dot—ideal for indoor alignment, positioning, aiming references, and OEM integration in measuring or indicating instruments.
