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 1 to 3µm wavelength region. Our B Series lead selenide (PbSe) detectors deliver the best overall performance in a wider spectral range from 1 to 5µm. Our multichannel (MCDs) devices are ideal for simultaneous detection of multiple gases including CO2, CO, and other hydrocarbons.

What's New

Opto Diode Corporation, an ITW company, introduces a high-performance, two-stage, cooled, lead selenide (PbSe) detector that operates in the mid-infrared (IR) spectral region with peak sensitivity between 4.3 and 4.5 µm. The cooler on the BXT2S-28T allows the detector element to operate as low as -45 °C to maximize detectivity (D*). The device also features excellent responsivity of 7.5 x 104 V/W (typical). The exceptionally reliable detector provides the highest sensitivity when monitoring small changes in gas mixtures.
