Listing is for a single 1.6W 450nm laser module. Unit is upgraded with a copper module for max cooling and stability. It is prewired with a 1.8A X-Drvie bucking laser driver and comes with a 405-450nm coated three element glass lens. The unit is ready to be dropped into your final project. No setting current or soldering diode to driver. Just place in heatsink and connect leads to your power supply.

Osram 1.6W PLTB450B 450nm Laser Diode



Input voltage range is 6V-9V. Great for use with two Li-Ion's or Lipo's. Suggest two 16340/18350/18650 3.7V Li-Ion's. You can also use a 6-9V 2A wall adapter or bench power supply.

Here is what you get. The X-Drive is encased in the back of the model connected to the diode.






Modules are wired with extremely flexible 26AWG wire that is burn proof and makes for very easy soldering.
