　　Special advantages of the product

CIS-CM990 is a scientific grade cryogenic camera that performs excellently in the shortwave infrared band. This model is equipped with a Sony IMX990 InGaAs sensor and a square 5um * 5um pixel array. This chip has the characteristics of wide bandwidth (0.4um-1.7um) and high sensitivity. QE can achieve up to 77% O CIS-CM990 at 1200nm and has a wide range of applications in short wave infrared astronomical imaging, photometric measurement, optical communication, laser, optical experiments, and other fields.

CIS-CM990 includes a 25mm filter mounting component. A 25mm filter is a common type used in laboratory applications, and SWIR (short wave infrared) filters can be easily installed inside the camera. The camera can achieve a rear intercept of 17.5mm with added filters to meet the requirements of compatible C-interface lenses.

CIS-CM990 has two versions: air-cooled and liquid cooled. Air cooling can achieve a temperature difference of -35C below ambient temperature. The liquid cooled version can achieve a temperature difference of -45C below ambient temperature using room temperature water, and can be reduced to an ambient temperature difference of -60 to -80Co using cold liquid. Due to the higher dark current of InGaAs sensors compared to conventional silicon-based materials, if you use this camera for long-term exposure (such as exposure>5 seconds), we recommend choosing the liquid cooled version.
