This listing is for ONE Brand New Nichia M140 M-Type 445nm 2+ Watt 5.6mm Laser Diode mounted in 12mm x 30mm Metal Housing Module w/ G-2 Glass Lens, Astral SuperDrive V Buck Driver & 22AWG Silicone Leads.

The driver is pre-set to 1.8 Amps. A 5V to 19V power source with sufficient current is required for operation. The module must be installed into a sizable heatsink to dissipate heat. Duty cycle will depend greatly on heatsink size. Active cooling will also help greatly with heat dissipation.

Driver Specifications:

V-in (V): 5 - 19V

V-out (V):  2.5 - 13V (depends on current output and laser diode’s Vf)

I-out (mA):  1100 - 5000+ mA*

Mode:  Buck Driver (step-down)

PWM Frequency:  1kHz

CP/CN/Floating:  Floating Output

Ripple:  Depends on ratio of V-out / V-in. At 5A and 4.5Vf output, ripple is about 1-2%

Current Setting:  Onboard Potentiometer

Dimensions (mm):  10mm x 15mm x 5.4mm

Notable Features: Current Regulated, Internal Soft-Start, Thermal Shutdown at 150°C

Please Note:
  1. Basic electrical knowledge and skills are required for setup and operation of this device. This product may not be suitable for everyone.
  2. Reverse polarity, excessive current and high heat will damage or ruin these. A proper CONSTANT CURRENT laser diode driver is required to drive the diode. The current is pre-set and should not be adjusted.
  3. Because the M140 laser diode is a multi-mode diode you will always get a rectangle as opposed to a dot. This is a characteristic of multi-mode laser diodes. The closer you can get the lens to the work the smaller that rectangle will become and the finer the detail you can achieve. You want to focus it so you have the cleanest and thinnest line possible. Don't try to make it symmetrical or you will produce a larger and less powerful beam. Be aware that the closer you get it to the work the more likely you are to get smoke and/or soot on the lens. A secondary air assist fan will greatly help reduce that risk. If you do get smoke on the lens the beam will start to look blurry. It can be cleaned with a very soft lens cloth and some 91% rubbing alcohol.
  4. This is a very powerful device and you must never shine it at another person, animal, aircraft or another persons property. This is NOT a toy! You are solely responsible for it's use. Always wear protective eye-wear that is rated to block the 400-470nm wavelength and NEVER look directly at the beam. You only have one set of eyes!
  5. Due to the volatile nature of electronics of this type, returns will only be accepted in original, sealed packaging.
I usually ship the same day or before the next available pick-up is available. Once your order is placed it will go out right away because I don't want you to have to wait any longer than you have to. Most orders are delivered within 3 business days in the continental U.S. International orders may to 4 to 6 weeks for delivery. Please choose an expedited shipping option to receive it sooner.

Please don't hesitate to contact me with ANY questions regarding my listing(s). I can offer a lot of technical assistance and/or point you in the right direction to find the answers you are looking for. I am usually very quick to respond and I'm more than happy to help.
