ZWO ASI662MM

The ASI662MC/MM is equipped with the Sony-IMX662 rolling shutter CMOS. Boasting a 1/2.8” frame size combined with a 2.9μm pixel size, it features 2.07 million pixels (1920×1080), and possesses both high sensitivity and low read noise characteristics. In high-speed mode, it can output 107.6 frames per second, providing reliable support for planetary observation.

4 Unmissable Advantages

Large full well capacity, not easy to overexposure

The ASl662 adopts Sony lMX662 sensor with the latest technology.

Compared to the previous generation of sensors, it has very low readout noise and an extreme large full well capacity. This helps effectively avoid overexposure issues and also allow longer  exposures. In low light conditions, the camera performs excellent, capturing very clear images of celestial objects.

256MB DDR3 & USB 3.0

The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission.

No Amp Glow

ASI662 exhibits zero amp glow, no matter how long the exposure and how high the gain value. Since it is implemented directly at the hardware level, it does not require software control.

Note: This technology is implemented directly at the hardware level and requires no software control.

Camera Curve

Readout noise includes pixel noise, circuit noise, and ADC quantization noise. The lower the readout noise, the better. As can be seen, the readout noise of ASl662 is very low compared to CCD camera. The built-in HCG mode can effectively reduce the readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain.

When the gain is 252, the HCG mode is automatically turned on and the dynamic range to 11 stops.

Quantum Efficiency

The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio.

The peak quantum efficiency of ASI662MC is 91%.

Based on internal testing and calculation, the peak quantum efficiency of ASI662MM is 91%.
