Opto Diode manufactures high performance infrared detectors with a wide variety of active area sizes, cooling alternatives, packaging, windows, lenses, and filters options. These detectors are ideal for gas analysis, emissions monitoring, spectroscopy, process control, flame and fire monitoring. Our A Series lead sulfide (PbS) detectors provide the highest sensitivity in the 2µm to 4µm wavelength region. Our B Series lead selenide (PbSe) detectors deliver the best overall performance in a wider spectral range from 1µm to 5µm. Our multichannel (MCDs) devices are ideal for simultaneous detection of multiple gases including CO2, CO, and other hydrocarbons.
