Abstract

We conducted detailed in-lab tests on Balor 17F sCMOS camera, the latest model of Andor, for its performances, including gain, quantum efficiency, linearity, read noise, dark current, etc. We also evaluated the camera in terms of functionality considering the needs of astronomical observation. According to the tests, the camera’s performance is consistent with the official specifications, and to use the camera properly, liquid cooling is mandatory. The dark current in different areas of the sensor varies greatly. We also find that the sensor has a strong response at the short end of optical band. There are still some controversial issues in the camera to be further explained.
