Listing is for a single 9mm 7W NUBM44-V2(AKA NUBM47) 450nm laser diode mounted in a 12mm x 30mm copper module with solid thermal back half with diode base contact seat, wired with leads and paired with a high transmission DTR-G-8 glass lens.

We only use the highest quality 12mm Axiz standard copper module housings. They are house sourced and professionally machined from pure 99.9% C1100 copper for the most efficient thermal transfer. These modules will not have issues with the lens threading flaking and chipping away getting into the diode pocket and damaging the optics within the module like the cheaper sourced copper modules that are provided by other vendors. This also unit includes a solid thermal back half with a special lip machined to make pressured contact with the back of the diode for proper thermal management of higher power 9mm diodes.

Save yourself the headache of pressing and soldering. Just add heatsink and driver limiting the current to 4.5A or less. 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 or wall adapter. A laser driver limited to no more than 4.5A is needed to power this diode. If you run off a alternative power source like a bench power supply you are accepting the risk of doing so. Non Laser driver power sources can cause reduced life or even immediate damage.
Here is what you get. One NUBM44-V2 450nm diode mounted in a 12mm x 30mm pure copper module with leads and a DTR-G-8 glass lens.
