The ASI6200 Pro mono and colour cameras are now available!
The ASI6200MM Pro uses Sony’s latest back-illuminated IMX455 Full Frame format native 16-bit ADC sensor. It has 3.76µm, ultra-low 1.2e readout noise and an innovative breakthrough resulting in zero amp-glow.
Amazing Craftsmanship, Lightweight Body, Solid Image Quality
ZWO has been working hard to reduce the weight of the camera while improving the performance of the camera. After years of technical research and experience building cameras, ZWO was able to reduce the weight of the ASI6200 to 0.7KG.
Full Frame Format
The ASI6200MM Pro uses the full frame format. The sensor length and width are 36mm x 24mm and the diagonal length is 43.3mm. This is a 62MP camera with a small pixel size of 3.76um that can accommodate a large well depth of 51.4ke.
Native 16-bit ADC
The ASI6200MM Pro is ZWO's first batch of CMOS astronomy cameras with a 16-bit ADC. This 16-bit ADC is not a CCD 16-bit ADC. It can really achieve a dynamic range output of 14 stops. This significantly improves the image sharpness and contrast, and the color changes are smoother and more natural.
IMX455 Backlit Sensor
Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.
Sony has newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure.
The ASI6200MM Pro has excellent performance with a dynamic range of up to 14 stops. When the gain value is 100, the magical HCG high gain mode is turned on, greatly reducing the readout noise, and the dynamic range is basically unchanged. It is recommended to set the gain to 0 or 100 for deep space imaging.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of ‘amp glow’. As the ASI6200MM Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
With amp glow – 300 second exposure
ASI6200 frame with no amp glow – 300 second exposure
The ASI6200MM Pro includes a polyimide heater which is completely hidden under a protective window. The heater power is about 5W and can be turned off through software control to save power.
ZWO calculates that the QE peak value of the ASI6200MM Pro is above 80%.
Two-Stage TEC Cooling, Ultra-Low Dark Current
ASI6200MM Pro uses two-stage TEC cooling that can lower the CMOS sensor temperature to more that 35°C below ambient temperatures, which can greatly reduce dark current generation and sensor noise even with extended exposure times.
The unique dark current suppression technology can even further reduce dark current noise.
At a cooling temperature of 0°C, the dark current noise is only 0.003e/s/pix. This means a 300s exposure will only generate a negligible 0.9e dark current noise.
Note：The camera cooler requires an external 12V power supply to power the camera instead of USB 3.0/2.0
USB 3.0 & 256MB DDR3 Memory
The ASI6200MM Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission. For long exposures, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
