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
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.
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.
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.
36.9mm x 36.9mm sensor
High Quality Image Output
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.
