Item specifics

Condition:

New other (see details): A new, unused item with absolutely no signs of wear. The item may be missing the original packaging, or in the original packaging but not sealed. The item may be a factory second or a new, unused item with defects. See the seller’s listing for full details and description of any imperfections.

Listing is for a single 1.5W-2W M140 445nm blue laser diode mounted in a 12mm x 30mm copper module with leads attached and a three element 405/445 coated glass lens with focus adapter. 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. The three element glass lens will give the lowest divergence but has some splash and the 405-G-2 gives about 30% more power and has a cleaner output.

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.

Laser Driver - It Can Be Done!

I do offer a boost driver that is capable of driving these diodes off a single Li-Ion. See this listing.

1.7A FMT V2 buck/boost driver

If this is your fist laser build here is a great place to start.

Diodes are sensitive and should not be run or soldered on until pressed in a module/heatsink. laser diodes also are current hungry and should never be run without a current limiting 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.

The Aixiz 405/445 Three Element Glass or the Single Element 405-G-2 lenses are the most commonly used with these diodes in conjunction with a 12mm Aixiz module as the diodes housing. I offer all the above as well as combo deals for them pre-assembled

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.;)

Current vs Output Plot

If you want to drive your diode off a variable power supply her is the process to use. If you choose to direct drive a diode you do so at your own risk. Not all power supplies are clean enough to direct drive a diode and a star-up spike could kill the diode.

Start with nothing connected to the power supply, turn it on and turn the current to zero. Set the voltage to 4.6V and turn the power supply off. Short the output leads on the power supply together than connect your diode.(very important step) Turn on the power supply and adjust your current to your desired. With 445 the voltage should be set to about 4.6V but it will vary by a tenth of a volt or two at 1.8A. If you need more headrooom with the voltage as it caps you at a certain current which is lower than your desired then repeat the process and up the voltage in 0.1V increments until you get the desired result.
