Astronomy
Whether it is the exploration of the universe by scientists or the observation of the bright starry sky by astronomy enthusiasts, astronomical cameras need to support ultra-long exposure with extremely low noise. Our sensor portfolio combines the characteristics of high frame frequency, low read out noise and high sensitivity, and can reduce the impact of dark current noise through the superposition of multi-frame short exposure images. Gpixel line of GSENSE and GLUX image sensors also have high dynamic range characteristics, which is a popular choice for astronomers and astronomy enthusiasts.
