94% QE
Scientific CMOS Camera

The QHY2020 uses a 13.3mm x 13.3mm square scientific CMOS with ultra high QE and wide spectral response from 200nm to 1100nm. It has 94% peak QE at 550nm-600nm, 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-
Count Photons

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. This detection limit is close to some EMCCD cameras.

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 with one channel at high gain and one channel at low gain. You can also select either the high gain or low gain output.

TE Cooling
━━━━

-40C Delta
Temperature Regulated

The QHY2020 has dual stage TE cooling that reduces the sensor temperature to -40C below ambient. TE cooling reduces the dark current significantly for clear, long exposure images.

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.

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 .

Spectroscopy

The high, wide response from NIR to UV makes the QHY2020 a perfect camera for spectrum analysis and spectrum imaging systems.
