ZWO ASI6200MM PRO [MONO]

The ZWO ASI6200MM PRO is a high resolution camera with a full-frame back-illuminated 16-bit Sony IMX455 sensor, featuring a QE up to 90%.

Sony’s back-illuminated CMOS technology improves sensitivity, minimizes noise, reduces power consumption and increases data download speed. In a conventional front-illumination structure, the interconnection of metal wiring and transistors are above the photosensitive silicon surface (photo diode), reducing the overall sensitivity and therefore the quantum efficiency. In back-illuminated sensors, the photosensitive surface is placed on top of the wiring so the incoming light is not obstructed, resulting in a greater quantum efficiency. Sony has developed a new and unique photo-diode structure and an on-chip lens that is optimized for back-illuminated structures, achieving a higher sensitivity and a lower random noise.

The ASI6200MM Pro is the first ZWO camera with a 16bit ADC that can achieve a dynamic range output of 14 stops. This improves the image sharpness and contrast significantly and the color shades are smoother and more natural.

When the gain value is 100, the HCG high gain mode is automatically activated and the readout noise is greatly reduced while the dynamic range basically remains unchanged. 

The ZWO PRO cameras incorporate a 256MB DDR3 memory buffer that improves data transfer reliability and it minimizes amp-glow caused by slow data transfer speeds. The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 9fps at full resolution.
