Hamamatsu unveils non-cooled InGaAs NIR sensor
Hamamatsu Photonics has announced the G1682x series, a compact InGaAs linear image sensor designed for near-infrared (NIR) multichannel spectrophotometry.
This front-illuminated range of sensors offers high sensitivity and an uncooled design, enabling rapid and accurate real-time analysis across a diverse range of applications for R&D, industrial, and original equipment manufacturer use.
The G1682x series allows users to conduct simultaneous analyses across multiple channels. With the same outline dimension as the previous G9203-256DA sensor, and single video line data output, the latest sensors significantly enhance efficiency and ensure thorough data collection, making them an indispensable tool for quality control, process optimisation, and various research applications.
Th designed combines an InGaAs photodiode array with a CMOS chip for stable operation in the near-infrared range of 0.9 to 2.1 µm. Users can optimise performance via adjustable conversion efficiency, selecting between two settings (CE=16 nV/e- and CE=160 nV/e-) through external voltage. This adaptability makes the G1682x series suitable for industrial, R&D and OEM requirements.
Unlike previous long-wavelength models that required TE cooling to mitigate dark current, the G1682x series maintains low dark current through zero bias operation, effectively eliminating the need for cooling, according to Hamamatsu.
The sensor operates at a drive voltage of just 3.3 V, and with pixel sizes measuring 50 µm × 250 µm for the G16823-128DB sensor and 25 µm × 250 µm for the G16823/G16824/G16825-256DG.
