Each housing includes a spring for secure diode contact and supports mounting a 10x20mm circuit driver inside, making it an ideal solution for professionals seeking reliable, compact, and efficient laser diode assemblies. ## Description Features: Material: Metal Color: Silver Lens: With 200-1100nm Plastic lens Inner Diameter: 10.3x40mm Outside Diameter: 12 x 40 mm (excluding the cap) Note: 1. 10x20mm circuit driver can be mounted inside 2. Diode housing for TO-18 laser diode! 3. With spring! It can help the diode contact the housing more tightly Package: 3pcs TO-18 5.6mm Laser Diode housing with Lens and spring and cap Review: Good item - Nice little diode host. The lens pitted, but it's to be expected if there's any power being sent. Better glass collimator rounded things out. Heat transfer was good thru the body and into aluminum sink, without lithium grease. Add that for optimal heat sinking. Review: Too small of a hole for an actual TO-18! - How frustrating! This collimator appears well designed, looks good, and has a nice lens focusing feature. However, the standard classic LTLD505T Laser diode which is a true TO-18 case with a specification of 5.6 +0 - 0.3 mm and a measured size of 5.60 mm fit CANNOT into a hole actually finished at 5.42 mm! The specifications for this collimator says it is actually for a 5.6 mm diameter diode (TO-18), but it is measured at 5.42. That's undersized by over 3%. High-chrome Steel on Brass and nothing budges! You have to epoxy it in place and hope it lines up? What a shame. All they had to do was drill it slightly larger! Press fit wouldn't be bad, but there are no signs that press-fit was intended. Who wants to crush their laser diode trying? ## Features - Diode housing for TO-18 laser diode! - Inner Diameter:10.3 x 40mm, Outside Diameter:12 x 40mm - Material: Metal, Color: Silver - Lens: With 200-1100nm Plastic lens - 10x20mm circuit driver can be mounted inside ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019MZAR7E | | Best Sellers Rank | #139,524 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #17 in Diode Lasers | | Brand | Lilly Electronics | | Brand Name | Lilly Electronics | | Color | Silver | | Customer Reviews | 4.0 out of 5 stars 41 Reviews | | Manufacturer | Blaser | | Material | Metal | | Material Type | Metal | | Style | Traditional | | Style Name | Traditional | ## Product Details - **Brand:** Lilly Electronics - **Color:** Silver - **Manufacturer:** Blaser - **Material:** Metal - **Style:** Traditional ## Images ![3pcs Silver Metal Laser Diode Housing 12x40mm for 5.6mm To-18 Laser Diode with 200-1100nm Collimating Lens - Image 1](https://m.media-amazon.com/images/I/51GO2Ekkg8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good item *by C***R on June 4, 2025* Nice little diode host. The lens pitted, but it's to be expected if there's any power being sent. Better glass collimator rounded things out.

I have not pressed a diode yet, it should work just fine. I'd drill a bigger hole if it's too small. Looking forward to use dvd burner diode and press it inside! ## 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.com.kw/products/24658703-3pcs-silver-metal-laser-diode-housing-12x40mm-for-5-6mm](https://www.desertcart.com.kw/products/24658703-3pcs-silver-metal-laser-diode-housing-12x40mm-for-5-6mm) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-13*
