    ZWO ASI461MM-Pro 100Mp Camera



    100Mp camera from ZWO

    Large sensor size of 44mm x 33mm

    3.76um Pixels


    ZWO ASI461MM-Pro adopts Sony medium format IMX461 sensor. It has the native 16-bit ADC with 65536 levels, back-illuminated structure and high quantum efficiency, and a great performance in DSO imaging. Milky way imaging and scientific research.

    It features very low readout noise and nearly zero visible fixed pattern noise.

    100 mega Pixels of 11656 x 8750. The 3.76 um pixel accommodates an impressive full well capacity of 50.3ke. While at Bin2 mode, you can get and even larger full well capacity of 198e and a large pixel size of 7.5um x 7.5um.

    ASI461MM-Pro is a 100MP camera with a large sensor size of 44mm x 33mmand a high resolution

    Note: External Power supplies are need for all ASI cooled cameras.  We recommend you use a 12v@3amp DC adapter (5.5 x 21. Center Pole Positive)

    No Amp Glow

    Traditional CMOS sensors produce a weak infrared light source during operation, which is often seen in the corners of uncalibrated images. This is a tell-tale sign of “amp glow”. As the ASI 4612MM-Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.

    Anti -Dew

    ASI461MM-Pro come with a polyimide heat that sits on top of the protective window. It will heat the window to avoid dew problems.

    The power consumption of the heater is around 5W. You can turn this function off in your imaging software if you want to save power.

    Camera Performance
    HCG Mode

    ASI461MM-Pro is integrated with HCG mode, which can get help greatly reduce readout noise and keep the dynamic range at a high level when you’re using higher gain.

    Set gain 100, then the HCG mode will be automatically turned on. The readout noise can be very low, while the dynamic range is basically unchanged.

    Quantum Efficiency

    QE curves and readout noise are two of the most important elements to measure a camera’s performance. Based on our calculations, the QE peak values  of ASI461MM-P is 91% @ 460nm

    Absolute Quatum Efficiency

    Relative Quantum Efficiency

    Two Stage TEC Cooling

    The TEC cooling system of the ASI461MM-Pro can precisely control the temperature of the sensor, and lower it to 30 – 35 degrees C below ambient temperature
