5 pack 12 x 30mm Copper 3.8mm Laser Diode Mount Blank Module & Diode Press Tool

Listing is for five Aixiz style copper modules designed for 3.8mm diodes and a self centering diode press tool. The module is 12mm X 30mm assembled and comes with an acrylic lens, focus ring, spring, copper diode housing and aluminum(not brass) back half/driver compartment. This is a perfect module for easy mounting in a 12mm heatsink which is pretty much the standard in the laser DIY trade. The unit is perfect for 3.8mm diodes of all types; 445, 405, 635, 650, 660 and IR diodes. Although it comes with an acrylic lens it is also designed to accept any M9X0.5 threaded lens including the most common used three element Aixiz glass lenses and the single element G-1/G-2 lenses. If you need a three element or a G-2 lens I also offer them. See my other listings
