## Overview

The Laser Module 850nm IR50 MW Diode is a compact, energy-efficient infrared laser dot generator operating at 850nm wavelength. Designed for professional use with a low voltage DC3-5V input and under 50mA current, it delivers precise, invisible targeting ideal for integration with infrared cameras and diode drivers. Its durable copper build and reliable operation within 0-30°C make it a must-have for advanced measurement and alignment tasks.

## Description

Wavelength :850nm Laser Shape:DOT Operating Voltage:DC3V-5V Operating Current: <50mA Operating temperature: 0 - 30 °C Size:12mm(D)*35(L) mm Packing:1X 850nm laser module

Review: Hot It's Not - Shipped quickly, worked, no problems. I was hoping that the optical power of the dot, focused, would be enough to, at least, make me say, "Ouch" - however - it's not that powerful. (My pic shows the dot via the smartphone imager, but you can't see it otherwise.) The circuit board that's attached gets pretty hot, and the wires, but not the desired result. Infrared doesn't equate to 'heat', at least not at this level.
Review: Not a Dot IR Laser - This product works well BUT I received a bar IR laser and NOT a dot IR laser so I need to now purchase something else. Plan accordingly if this matters to you.
