Light-Sensitive, Backlit IMX455 Sensor

The back-illuminated CMOS image sensor from Sony provides sensitivity and noise reduction essentially unmatched in most cameras of the same class. These are two of the key factors when looking to enhance your image quality. Native to CMOS sensors, the IMX455 also functions with extremely low power consumption while maintaining high-speed operations.

Camera Performance and Cooling

The ZWO ASI6200 has a dynamic range of up to 14 stops and quantum efficiency of 80%. Under this operation, a two-stage TEC cooling system is used to lower the CMOS sensor temperature to 35 degrees below ambient temperatures, greatly reducing dark current generation and sensor noise even during long exposures. Dark current suppression technology is also integrated into this camera for further reduced noise. 

At a cooling temperature of zero degrees Celsius, the dark current noise is only 0/004e/s/pix, meaning a 300s exposure will only cause 1.2e of dark current noise!
