ZWO ASI662MM IMX622 Mono Astronomical Planetary Camera 1920x1080 USB3.0 12Bit ADC Built-in 256MB DDR3
Description:
- The ASI662MM is equipped with the IMX662 rolling shutter CMOS. Boasting a 1/2.8” frame size combined with a 2.9μm pixel size, it features 2.07 million pixels (1920x1080), 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.
Large full well capacity, not easy to overexposure:
- The ASI662 adopts for Sony IMX662 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 ASI662 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 12bit.
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.
- Based on internal testing and calculations, the peak quantum efficiency of ASI662MM is 91%.

- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not. Regardless of legal demands, you may find that your company needs one or more legal pages for compliance and optimal operation.
- In this article, we will go over the most common legal pages, walk you through a summary of what each requires, and explain why you may need it. In addition, you'll find a sample template for each type of legal page so you can quickly get started writing your own.
