808nm 300mW Infrared Laser Diode | 2.2V TO-18 High-Power IR Laser Module for DIY Lab & Optical Projects

Product Description

The 808nm High-Power Infrared Laser Diode (TO-18 package) is a precision-engineered infrared (IR) laser source designed for DIY laboratory projects, optical research, alignment systems, and laser experimentation.

Operating at 808 nanometers (near-infrared spectrum), this 300mW laser diode produces an invisible but powerful IR beam, making it ideal for pumping solid-state lasers, optical fiber testing, or infrared illumination.
Housed in a TO-18 metal can package, it provides excellent thermal stability, long service life, and consistent power output when properly driven.

⚠️ Note: The 808nm beam is not visible to the naked eye. Proper IR-rated laser safety goggles are required when operating this device.
