QHY4040 FSI Cooled Scientific Cameras (CMT, CMN)

Large Area Sensor, 36.9 x 36.9mm 4K x 4K
The QHY4040 uses a GSENSE4040FSI front-illuminated, 16.8 Megapixel, 36mm square, scientific CMOS image sensor. With a five transistor (5T) HDR pixel design and a 9μm pitch, the sensor can achieve 3.7e- read noise and 74ke- full well capacity in HDR mode. The QHY4040 camera achieves 20 FPS at full resolution with USB 3.0. This makes the QHY4040 an ideal camera for various applications.

QHY4040 - Spectral Response

Multiple Pixel Clocks, 20 FPS at Full Resolution
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.

74% QE, 86dB Dynamic Range, 3.7e- Read Noise
Currently, the QHY4040 is only available in a front illuminated version. 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.

Dual Stage Regulated TE Coolling -35C
The QHY4040 has 2-stage thermoelectric 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.

Astronomical Imaging, Biological Imaging, X-Ray Imaging, Dynamic DR
The high sensitivity, large field of view, 9um pixel size and large dynamic range are all ideal for astronomical imaging.  The large 36.9mm x 36.9mm sensor with high resolution, high quality Image output also makes the QHY4040 ideal for Biological imaging.  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.
