Raptor Photonics announced its new Ninox 640 SU, a vacuum cooled to -80°C InGaAs camera, offering ultra-low dark current for longer exposure times up to 5 minutes. Combining a low read noise of <56e- in high gain and a dark current reading of <300e/p/s at -80°C, the Ninox Ultra is one of the most sensitive SWIR cameras available on the market and perfect for imaging weak signals using longer exposure times. It offers a resolution of 640×512 and has a 15µm x 15µm pixel pitch.
The camera also offers a high intra-scene dynamic range of 56dB in high gain, enabling simultaneous capture of bright and dark portions of a scene. The Ninox 640 SU follows on from the launch of the Ninox 640 and Ninox 1280 cameras, which have attracted a lot of interest in applications including astronomy and in-vivo imaging. The Ninox 640 SU is also available for sale in China and Russia.
