Large active-area InAsSb detectors for room-temperature MWIR sensing: Technical considerations for legacy PbSe technology replacement

02 October 2026

Hamamatsu Photonics’ application note assesses large-active-area InAsSb photovoltaic detectors as room-temperature alternatives to legacy PbSe technology for MWIR sensing. Comparing factors including speed, linearity, stability, optical throughput, and lifecycle considerations, it provides engineers with a system-level perspective on selecting InAsSb for NDIR, industrial monitoring, and analytical applications.
