The beam is extremely weak, I would recommend a laser diode with at the very least 100mw to burn anything. I hope this helps. **Q: How fast can this laser be modulated by modulating the input voltage?** A: The input voltage does change the brightness of the laser. There is a protective circuit limiting voltage and brightness that could affect response time but it is likely to work. But why use UV when green is easier to see and red is dirt cheap? **Q: Is this laser for a scanning microscope? Can anyone recommend a sensor?** A: The beam quality appears to be single mode with no ghost spots. It could be used as a source if it is truly CW and if one wanted to scan at this wavelength. **Q: How many are there, two?** A: No,the price is one piece ## Frequently Bought Together - Laser Module 405nm Violet Purple Blue Laser "Dot" Diode (Adjust Focus 5mw DC3V-5V) - Green Laser Modules GM532-50 (DOT Laser) Diode Modules 2 Pack (Solder Wires) - HiLetgo 10pcs 5V 650nm 5mW Red Dot Laser Head Red Laser Diode Laser Tube with Leads Head Outer Diameter 6mm --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/439759684-laser-module-405nm-violet-purple-blue-laserdot-diode-adjust-focus](https://www.desertcart.hr/products/439759684-laser-module-405nm-violet-purple-blue-laserdot-diode-adjust-focus) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-03*
