Listing is for a single 5.6mm Osram PLTB450B 1.6W 450nm laser diode mounted in a 12mm x 30mm copper module with leads attached.. The copper module upgrade provides a huge  improvement  in thermal  conductivity over the standard brass module for moving the heat away from the diode to your heatsink which gives a much more stable output from the diode. Please Note this module comes with an acrylic lens in it to keep dust out. It can not handle the power  this unit can put out. It will keep contaminates out of the  module until you are ready to put yours glass lens in. Replace with your glass lens of choice before powering the module. The best options are the Three Element(Aixiz)  405/445 Glass  Lens or the 405 G-1 Lens. If you need a lens with the unit I do offer this unit in a combo with a three element or with the G-2. See my other listings.





Check out this thread for details.




 Save yourself the headache of pressing and soldering. Just add host, heatsink and driver. The  current must be limited to no more than 1.8A to the diode.

Wire assignment is:

Red +

Black -


Diodes are current hungry and as they heat up their internal resistance is lowered causing them to want to draw more current. Don't attempt to connect the diode directly to a fixed voltage source like a battery. You must use a "constant current" power source like a current limiting driver or variable current power supply with the current limited to no more than 1.8A or you diode will suffer thermal runaway and die. For more info on the reason for a constant current driver see this thread.
