2W M462 462nm Blue Diode in Copper Module W/Leads & G-2 Glass Lens

Listing is for a single 2W M140 445nm blue diode mounted in a 12mm x 30mm copper module with leads and a high output 405-G-2 Glass Lens. 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. Save yourself the headache of pressing and soldering. Just add host, heatsink and driver limited to no more than 1.8A. The three element glass lens will give the lowest divergence of any lens available but has some splash and the 405-G-2 gives about 30% more power and has a cleaner output. I also have a combo with the three element lens instead of the three element. See my other listings.;) Wire assignment is: Red + Black - White Case A laser diode is a current-driven device which is should not to be driven by a voltage source. Otherwise electrical overstress may occur to the laser diodes as the operation voltage varies from device to device and additionally depends on the case temperature. Special care has to be taken, when switching the electrical power on and off, as transient currents beyond the maximum ratings can occur damaging the laser diode. To operate laser diodes correctly , a proper electrical driving mechanism has to be employed. A proper laser diode driver must act as an accurate constant current source with good transient protection and very low noise. Furthermore, please note that at different temperatures the output power of the laser diode will change. Thus, for applications that require a constant output power over a broad range of temperatures active temperature control is necessary.
