This listing is for ONE Brand New Nichia NUBM44 v2 or NUBM47 445-450nm 7-Watt 9mm Laser Diode Mounted in a 12mm x 28mm Solid Copper Housing Module w/ G-7 Lens and 22AWG Silicone Leads w/ JST Connectors. This Version Has More Threads Which Accommodates the G-7 Lens Much Better Than Other Versions.

Solid copper back half of module for maximum heat dissipation.

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 should not exceed 4.5 amps.
  3. Because the NUBM44 laser diode is a multi-mode diode you will always get a rectangle as opposed to a dot. This is a characteristic of all 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 eyewear 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.
