ZWO ASI990MM Pro USB3.0 Monochrome SWIR Camera

Product Image

The ASI990MM uses the 1/2" Sony IMX990 SenSWIR sensor, featuring a wide band from 0.4μm to 1.7μm.
This is the first and most powerful SWIR camera by ZWO.

    The camera has a large full well capacity and high sensitivity with a large QE peak value of 80% at 1200nm and a big pixel size of 5μm.

    The great performance in capturing short wave infrared lights makes it applicable for SWIR imaging, photometric measurement, optical communication, laser and optical laboratory and more fields.

    Penetrate through the cloud and fog and capture stars in the daytime.
    The ASI990MM can capture high-definition images.
    The wideband (0.4 to 1.7μm gets the camera's sensitivity into a higher level, making it capable of capturing beautiful night skies with thin clouds and also allows you to photograph stars during the daytime.

    No Amp Glow
    Traditional CMOS sensors produce a weak infrared light source during operation, which is quite often seen in the corner of uncalibrated images.
    This is a tell-tale sign of 'Amp Glow'. As the ASI990MM Pro uses zero amp glow circuitry, there is no need to worry about amp glow any longer.

    Camera Curve
    Readout noise is generated in the amplifier on the ship that converts the stored charge of each photodiode (ie pixel) into an analogue voltage to be quantified by A/D conversion.

    Quantum Efficiency
    QE curve and readout noise are two of the most important elements to measure cameras' performance. based on our calculation, the QE peak value of ASI990 is over 80% at 1200nm.

    Two-stage TEC Cooling
    The TEC cooling system can control the temperature of the sensor to 30-35 degrees below ambient temperature.
    it is recommended to use the camera at low temperatures so to get better imaging performance.
