OSC Planetary Camera with High Sensitivity
The ASI662MC adopts the Sony-IMX662 sensor, has a rolling shutter, a frame size of 1/2.8", a pixel size of 2.9um, and has 2.07 million pixels (1920x1080). In high speed mode the CMOS sensor can output 102.6 frames / second at full resolution and provide a low read noise level.
Large Full Well Capacity
The ASI662MC adopts Sony IMA662 sensor with the latest technology. Compared to the previous generation of sensors, it has very low readout noises and large full well capacity which is 3 times larger than the IMX 462MC. This helps effectively avoid overexposure issues and also allows longer exposures. In low light conditions, the camera performs excellent, capturing very clear images of celestial objects.
ASI662MC adopts the latest SONY IMX662 sensor with the advanced STARVIS 2 technology. Featuring zero amp glow, higher sensitivity to red and near infrared (NIR) light, and 3 times larger full well capacity, it can be regarded as an upgrade of ASI462MC. Also, its dark current noise is lower than the ASI174MC.
USB 3.0 & 256M DDR3 Memory
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. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
The ASI662MC is an upgraded product of the ASI462MC. Compared to the ASI462MC, it has the characteristics of a greater full well depth and no amp glow.
No Amp Glow
ASI662 MC 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.
Camera Curve Low Read Noise, High Dynamic Range
The 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 ASI662MC 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 rises back to 12bit.
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.
