Looking at these as an upgrade from the standard brass modules they are made from pure copper that will provide maximum thermal conductivity and they have an aluminum back half for better heat transfer through the rear threads of the module. The module is 12mm X 30mm assembled and comes with an acrylic lens, focus ring, spring, copper diode housing and aluminum back half/driver compartment. This module is designed for easy mounting in a 12mm heatsink which is pretty much the standard in the laser DIY trade. The unit is perfect for 5.6mm 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 405-G-1 / 405-G-2 lenses. If you need a three element or a G-2 lens I also offer them. See my other listings Review: Great Modules - Each one works great, with zero play for the diode. i got a salvaged red 250mW in Two, and a Bluray 440nm in another, A tip for anyone complaining about the hole being too small for your diode, Use the back of the module or anything else that has a hole where only the diodes legs can fit into, Then Use a c-clamp or Vice to slowly press fit the diode into the copper piece, There are a lot of videos showing how to do this. Review: Very good for the price - These work great, I've used 2 of the 3-pack that I bought. I also bought the press kit which does help to get the diode seated nicely. I was able to swap the lens out with some others that I had bought elsewhere. I was also able to put the copper part into a larger heat sink which is working very well. I agree with another reviewer that having both pieces made out of copper would be better for heat sinking and give this the full 5 stars. I have no regrets on this purchase and plan on buying more of these if/when I get more diodes. ## Features - 3 pack 12 x 30mm Copper 5.6mm Laser Diode Mount Blank Module ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.8 out of 5 stars 7 Reviews | ## Images ![3 pack 12 x 30mm Copper 5.6mm Laser Diode Mount Blank Module - Image 1](https://m.media-amazon.com/images/I/71Mjy05CCKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Modules *by R***N on January 1, 2018* Each one works great, with zero play for the diode. i got a salvaged red 250mW in Two, and a Bluray 440nm in another, A tip for anyone complaining about the hole being too small for your diode, Use the back of the module or anything else that has a hole where only the diodes legs can fit into, Then Use a c-clamp or Vice to slowly press fit the diode into the copper piece, There are a lot of videos showing how to do this. ### ⭐⭐⭐⭐ Very good for the price *by M***R on December 14, 2014* These work great, I've used 2 of the 3-pack that I bought.

Far better quality that the other cheap housings you will find. The diode / lens section is copper, and the tube is aluminum giving you far better thermal properties. The guy complaining about his diode not fitting is clearly unaware that you must press the diode in with a press tool (or a homemade tool like i use) this is a plus as the diode will make good thermal contact with the housing. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/12783906-3-pack-12-x-30mm-copper-5-6mm-laser-diode](https://www.desertcart.co.uk/products/12783906-3-pack-12-x-30mm-copper-5-6mm-laser-diode) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
