Item specifics

Condition: New: Never Used  
Listing is for a single 5.6mm M140 445nm diode and a bare collimating lens that the diode is paired with in the projector and is for experimentation only. An Aixiz 405/445 Three Element Glass or the Single Element G-1 lenses are the most commonly used with these diodes.  These are the new M140 diodes that have been showing great improvements over the A140 diodes. These 445 diodes are rated @ 1W from the manufacturer and with a Aixiz three element glass lens being driven @ 1.8A they will fall between 1.5W-2.1W and with a G-1 lens it will fall between 1.7W-2.4W.

These moudles are now using the more efficent M140 diodes from the new 3000 Lumen projectors. They have shown an average increase in efficiency of the previous A140's. See this thread for details.

This is the new M140 diode that everyone has been talking about. They come from a well known DLP projector being extracted the safest way by using a no heat non pin stressing method. A lot of seller will not want to take the time to do this and will just use a soldering iron and this can burn the glue that holds the pins in place. Leading to diminished life of your diode.

Max suggested current is 1.8A to the diode. Don't attempt to connect directly to a battery you must use a current limiting driver. I do offer a boost driver that is capable of driving this diode off a single Li-Ion see my other offerings below.

Diodes are sensitive and should not be run or soldered until pressed in a module/heatsink. laser diodes also are current hungry and should never be run without a current limiting driver. Check my other items below for an appropriate driver.

Diodes are tested to be in working order and packaged in an antistatic bag. Please use ESD precautions and short your driver leads discharging any capacitors before hooking up your driver to the diode.
