Scientific CMOS Cameras

High QE, Low Noise

The QHYCCD scientific back-illuminated CMOS camera has an ultra-high quantum efficiency of 95%, providing strong support for low-light applications, especially for video low-light applications.

Low Noise

Dual Stage TE cooling
Ultra-Low Read Noise

The ultra-low read noise of 1.3e- to 1.7e- gives this series of scientific cameras the ability to detect signals in extremely low light conditions. Combined with their high QE they are able to reach the level of detection of several photons.


Live Video

Our scientific CMOS cameras uses a USB3.0 transmission interface with 24 frames per second real-time video capture capability for 2K devices. This frame rate supports 8-bit and 12-bit transmission at the same time. The video is smooth and easy to use.

Multiple Sizes

Meet Image Requirements

QHY scientific CMOS cameras are available with sensor sizes of 1.5-inches, 2-inches, up to 36.8mm x 36.8mm, to meet a variety of target imaging requirements. The large target area sensor of 36.8mm x 36.8mm is suitable for X-ray dynamic DR shooting, real-time imaging of large-caliber astronomical telescopes and dynamic space debris monitoring. The 2-inch product is suitable for use with large aperture photographic lenses, such as 50/0.95 lenses, for night vision low-light imaging, forensic UV imaging, and power line UV imaging.



The QHY42 is a cooled scientific camera using the GSENSE400BSI Scientific CMOS sensor featuring extremely low (1.3e-) read noise and a back-side illuminated sensor with 95% peak QE, 79% QE in the 240nm UV band. We also offer the QHY42-BSI in a UV enhanced version as well as a front illuminated version. The sensor array is 2048 x 2048 with relatively large 11um pixels and 89ke- full well capacity. The QHY42 is capable of high frame rates up to 24FPS at full resolution. Two stage TE cooling lowers the sensor temperature to -40C below ambient. The QHY42 is ideally suited to scientific research, astronomy, biology, UV and low light imaging, and security.


The QHY2020 uses a GSENSE2020BSI CMOS sensor. Back-Illuminated, 2K x 2K @ 6.5um, the QHY2020 features read noise of 1.6e-, full well of 54ke-, and a peak QE of 94%. The camera is offered in two variations: -H and -M. -H has better MTF and higher Full well capacity, while -M has lower dark current.


The QHY4040 uses a GSENSE4040BSI Scientific CMOS, back-illuminated or front-illuminated, 4K x 4K @ 9um. The sensor is 36mm square and can achieve 3.7e- dark noise and 74ke- FWC simultaneously in HDR mode. Maximum frame rate at full resolution is 24FPS or 96FPS in binned mode. These features make GSENSE4040 an ideal image sensor for various applications. It is available in two variations: CMN and CMT. CMN is a monochrome sensor without microlens array and protected by a removable glass lid, which is ideal for X-ray imaging, charged particle detection, and micro-CT application; while CMT is a monochrome sensor with microlens array and sealed with D263T lids with anti-reflective coating on both sides, ideal for medical imaging and astronomy applications.


The QHY6060 uses a GSENSE6060BSI back-illuminated, 37.7 Megapixel, 61mm square (89mm diagonal), scientific CMOS image sensor with 95% QE and 90dB dynamic range. The sensor has a read noise of 4e- in rolling shutter mode. The GSENSE6060 supports CMS technique to further decrease dark noise and increase dynamic range. These features make GSENSE6060 an ideal image sensor for various applications, including professional astronomy applications.
