InAsSb Photovoltaic Detector, P17442-011MS

Hamamatsu Photonics’ new high-sensitivity InAsSb photovoltaic detector, P17442-011MS, is designed for fast mid-infrared measurement at wavelengths up to 5 µm. Developed as a RoHS-compliant alternative to traditional PbSe detectors, it combines strong spectral performance in a compact, non-cooled package.

Featuring a large 1 × 1 mm photosensitive area, the detector captures more incident light to help increase the output signal. Typical photosensitivity of 65 mA/W and detectivity of 1.0 × 10⁹ cm·Hz¹/²/W support reliable detection of weak signals. With typical peak sensitivity at 4.1 µm and a typical cutoff wavelength of 5.3 µm, it extends detection through the 5 µm band.

A fast 15 ns rise time enables rapid measurement and signal modulation without cooling. Excellent linearity and long-term stability make the detector well suited for broadband and high-power light sources over extended operating periods.

A sapphire window, broad 100° field of view and back-illuminated structure support versatile optical designs and improved temperature sensitivity. Housed in a high-reliability TO-5 metal package and rated for operation from −40 to +85 °C, the detector is ready for integration into demanding industrial and analytical systems.

The P17442-011MS is suited to gas detection, radiation thermometry and flame detection. Its spectral range supports gas analysis where gases exhibit characteristic mid-infrared absorption. For radiation thermometry, its fast response and back-illuminated design enable rapid remote sensing, while timely signal detection supports flame monitoring.

The detector is lead, mercury- and cadmium-free and meets RoHS requirements, helping optical system designers and integrators address restricted-substance requirements without compromising measurement capability. Non-cooled operation can also simplify system design by removing the need for dedicated cooling hardware.

The P17442-011MS expands the options available for mid-infrared sensing and reflects Hamamatsu Photonics’ continued commitment to advancing detector technology for evolving industrial, environmental and research applications.
