QHY4040 has a 36.9mm x 36.9mm square sensor with 9.0um pixels in a 4k x 4k array and supports 20FPS full resolution live video.
High Dynamic Range
Low Read Noise
The QHY4040 camera uses a GSENSE4040FSI sensor with an image area of 36.9 x 36.9mm, 1.57 times larger than full-frame format, with higher resolution and image quality. The large area array has 9um pixels and an electronic rolling shutter, 86dB dynamic range, 3.7e- read noise and a peak QE of 74% at 600nm.
USB3.0 High Speed Interface
Multiple Pixel Clock 20FPS at Full Resuolution
The QHY4040 has a USB3.0 high-speed interface with up to 5GB of bandwidth. The camera achieves 1:1 video output at 20 frames per second (8-bit) with 4096 x 4096 resolution or 8FPS in low noise 12-bit mode. As different clock rates affect read noise performance, the QHY4040 supports five readout clocks and 8FPS, 12FPS, 16FPS, 18FPS and 20FPS frame rates.
-35C Below Ambient
Regulated Temperature Control
The QHY4040 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.
Currently, the QHY4040 is only available in a front illuminated version. A back-illuminated version of this sensor is rumored to be available in the future.
The QHY4040 has an ultra-high dynamic range of 86dB and an extremely low readout noise of 3.7e-. 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.
