Hamamatsu Photonics has introduced the P13243 detector, using an InAsSb sensor as an eco-friendly alternative to lead salt. It provides high sensitivity over the 2.5–5.3 µm range with detectivity peaking at 1 × 109 (cmHz/W). The detectors are uncooled and so have low power consumption. Since they are photovoltaic, they require much simpler electronics.
