QHY2020 BSI Cooled Scientific Cameras

The QHY2020 uses a GSENSE2020BSI back-illuminated scientific CMOS image sensor with 4.2MP resolution and 6.5μm pixel size. With six-transistor (6T) pixel architecture, GSENSE2020BSI features readout noise of 1.6e-, full well of 54ke-, as well as peak QE of 94%. The 13.3mm x 13.3mm array has wide spectral response from 200nm to 1100nm. It has 94% peak QE at 550nm-600nm and 60% QE at 240nm. It also has very good QE in the NIR range, 60% at 800nm, 38% at 900nm.

  • Ultra-Low Read Noise, 1.6e-
    With read noise as low as 1.6e-, this camera can capture photons from very dim objects. At 3.5 electrons it can achieve SNR=2, which means 4 photons. In addition, the sensor supports correlated multiple sampling (CMS). The read noise can be further reduced to 1.2e- with 2-CMS operation.

  • Efficient Two-Stage Thermoelectric Cooling
    The QHY2020 has two stage TE cooling that reduces the sensor temperature to -40C below ambient.
  • Astronomical Imaging
    With ultra high QE and ultra low read noise, the QHY2020 is an ideal camera for time-domain astronomy, autoguiding large professional telescopes, and transient source detection and spectrum analyze.
  • Biological Imaging
    The 13.3mm x 13.3mm sensor size is well matched to a microscope image circle. Microscopy applications will benefit from its high QE, low noise and fast readout. The QHY2020 is an ideal scientific CMOS camera for Fluorescence imaging .
Spectral Response QHY2020
  • Spectroscopy
    The high, wide response from NIR to UV makes the QHY2020 a perfect camera for spectrum analysis and spectrum imaging systems.
  • Dual 12-bit A/D, High Dynamic Range, Dual Image Output
    The effective image size is 2048 x 2048 pixels. However, it has the capability to output dual channels as 4096 x 2048 image with one half at low gain, high dynamic range and the other half at high gain, low read noise. The two ADCs will sample the same signal at the same time to generate the two images.
  • Electronic Rolling Shutter, Sensor free of Microlens
    The GSENSE2020 sensor has an electronic rolling shutter with Global Reset and does not use a microlens array over the pixels. Microlens are often employed to increase the quantum efficiency of the sensor by redirecting light from obscured areas of the pixel toward the photosites. This microlens effect can vary depending on the angle of incidence of the light cone making photometric calibration of large fields taken at low f/rations problematic. However, the back-illuminated GSENSE2020 achieves high quantum efficiency without microlens making it ideally suited to photometric calibration.
  • High Frame Rate, 43 FPS USB3.0
    The standard version of the QHY2020 is USB3.0. It can produce a maximum frame rate of 43 frames per second for 8-bit images, or 25 frames per second for dual 12-bit images. The camera can also transfer selected regions of interest for extremely fast rates, e.g., 430 FPS at 200lines, 4300 FPS at 10 lines, and 21,500 FPS at 2 lines. This specially addressed line readout mode can also be customized.
