Large Area Sensor | 36.9mm x 36.9mm 4K x 4K
QHY4040/QHY4040PRO uses the GSENSE4040 sensor, it has a 36.9mm x 36.9mm square sensor with 9.0um pixels in a 4k x 4k array. It has 36.9*36.9mm big image area. 1.57 times larger than full-frame format. With higher image quality and fast readout speed, it is an idea alternative for the KAF09000 and KAF16803 based camera.
Zero Amplifier Glow | Low Read Noise 4e-
Unlike the high readout noise of CCD sensor under high readout speed, even on ten frame per second, it has only 4e- read noise(at gain32) . It has a peak QE of 74% at 600nm. And the QHY4040/PRO has zero amplifier glow feature.
USB3.0 High Speed Interface | Multiple Pixel Clock 24FPS Frame Rate
The QHY4040 has a USB3.0 high-speed interface with up to 5GB of bandwidth. QHY4040PRO has both USB3.0 and 2*10Gbps Filber. 2*10Gbps fiber port support max 24FPS@16bit output. USB3.0 support max 20FPS@8bit and 10FPS@16bit ouptut. Camera supports different readout clocks and 8FPS, 12FPS, 13.3FPS, 16FPS, 18FPS,20FPS,24FPS frame rates.
Low Dark Current | -35C Below Ambient 0.05e/pixel/sec @ -15C
The QHY4040/PRO has 2-stage TE Cooling that reduces the sensor temperature to -35 °C below ambient. TE cooling significantly reduces dark current and produces cleaner, lower noise images over long exposures.
Front Illuminated | 74% QE Electric Rolling Shutter
Currently, the QHY4040/PRO is only available in a front illuminated version.A back-illuminated version of this sensor is rumored to be available in the autumn of 2020. QHY4040 has a rolling electric shutter, high reliability and stability than mechanical shutter when the observatory shoots a large number of pictures.
Astronomical Imaging
The QHY4040/PRO has an ultra-high dynamic range of 86dB and an extremely low readout noise of 4e-. This makes the camera exceptional for astronomical imaging, medical imaging, life sciences, fluorescence detection, trace sciences.
Biological Imaging
36.9mm x 36.9mm sensor High Resolution High Quality Image Output
Dynamic DR
For dynamic medical x-ray DR imaging the QHY4040 sensor size matches most industry-standard DR lenses and the high frame rate and low readout noise performance is ideal for X-ray imaging.
