Request InfoOpto Diode CorporationThe BXT2S-28T two-stage mid-IR detector from Opto Diode Corp. is a cooled, lead selenide (PbSe) device 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. The device also features a typical responsivity of 7.5 × 104 V/W, providing high sensitivity when monitoring small changes in gas mixtures. Real-time measurements are supported with a fast response time. The cooled unit delivers additional sensitivity for very low-level signal detection and enhanced stability for...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/4/2022Fiber Optic ConnectorsThe Amphe-Lite connector series from Amphenol Industrial Operations has been enhanced to meet the needs of fiber optic interconnection applications in the medical, oil and gas, security, and grid...Photonics.com 12/12/2022Optical Sensing InterrogatorsFemto Sensing International has expanded its SX line of optical sensing interrogators for high-sensor-count fiber Bragg grating (FBG) applications.
