Tried both ways of the lens. Build a jig to test this where I could place the lens from directly touching to 2 inches and had no good results. But when I placed a second lens in the jig, at the right distance, I got a tight spot. ## Frequently Bought Together - 3pcs Silver Metal Laser Diode Housing 12x40mm for 5.6mm To-18 Laser Diode with 200-1100nm Collimating Lens - Laser Component for DIY laser engraving machine PLPT5447KA 445nm 450nm Blue Laser Diode 1600mw 1.6w TO18 5.6mm - 405nm 445nm 450nm Laser Diode LD Driver Board 12V 2W Step-Down Constant Current Drive Circuit of TTL Modulation Power Supply --- ## 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.tn/products/24658703-3pcs-silver-metal-laser-diode-housing-12x40mm-for-5-6mm](https://www.desertcart.tn/products/24658703-3pcs-silver-metal-laser-diode-housing-12x40mm-for-5-6mm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-14*
