Listing is for a brand new single 500mW 635nm laser diode in a copper 12mm module with leads attached. MitsubishiML501P73-02 Please Note this unit comes with an acrylic lens in it. It is for those that want to use their own lens solution. It will keep dust and contaminates out of the module until you are ready to put yours in. Replace with lens of choice. Threading is M9X0.5 which is the most common threading used. The best options are the Three element Glass Lens or the 405-G-2 Lens.
Save yourself the headache of pressing and soldering. Just add heatsink and driver. The current must be limited the diode.(800mA max suggested). Don't attempt to connect directly to a battery or you will damage this diode. This is the diode that everyone has been talking about.Modules are fully tested to be in working order and the leads will have the ends twisted and soldered together for ESD protection. Please use all ESD precautions and short your driver leads discharging any capacitors before hooking up your driver to this module.
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 850mA or you diode will suffer thermal runaway and die. For more info on the reason for a constant current driver see this thread.
If you are looking for a host here are some of the more popular host/heatsink kits that will work with these diodes and if you want something that is not listed in those links that I show in my tutorials below shoot me a message and I can point you in the right direction for them.;)
