Teledyne 1802-0000-04 Retro Reflector Assembly

The Teledyne 1802-0000-04 Retro Reflector Assembly is a corner-cube retro reflector that returns the transmitted infrared beam to the optical head for continuous open-path gas measurement in Teledyne LightHawk open-path gas analyzers. Installed remotely at the end of the monitored path, it provides reliable beam reflection for open-path infrared absorption spectroscopy used to detect hydrocarbons and toxic gases. This OEM replacement from Teledyne Monitor Labs (Teledyne ML) carries manufacturer part number 1802-0000-04 and is compatible with Teledyne LightHawk Open-Path Gas Monitoring Systems (model dependent). Typical applications include refinery perimeter monitoring, petrochemical plants, chemical processing facilities, offshore platforms, pipeline leak detection, environmental monitoring stations, and industrial fence-line monitoring. Common replacements include TELEDYNE 1802-0000-03 and TELEDYNE 1802-0000-05.
