New InGaAs camera: High resolution, small pixel and low readout noise

23 February 2024

The new C16741-40U indium gallium arsenide (InGaAs) camera from Hamamatsu Photonics showcases a super extended graphics array (SXGA) resolution of 1280 x 1024 pixels and an extended sensitivity range spanning from 400 nm to 1,700 nm, encompassing both visible and short-wavelength infrared (SWIR) regions. Boasting 5 μm pixels, it excels in capturing high-resolution images with an exceptional signal-to-noise ratio, attributed to its minimized readout noise.Source: Hamamatsu PhotonicsSource: Hamamatsu Photonics

The camera integrates a Peltier element for efficient sensor cooling and temperature stabilization. The USB 3.1 Gen 1 interface port facilitates 12-bit image acquisition and exposure time adjustment, contributing to its overall versatility and performance.

The key features of this new InGaAs camera — high resolution, small pixel, and low readout noise significantly enhance the functionality of SWIR cameras across various applications from food and plastic sorting to silicon wafer inspection, laser beam alignment and solar cell evaluation.
