QHY2020 Scientific CMOS Camera
Important Note: Call us for a price for QHY2020UV & QHY2020EUV
Back Illuminated / EUVX | 94% QE / EUV Response 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. QHY2020EUVX is a special EUV/Soft X-ray enhanced version with >90% QE in 1.2nm to 15nm extreme UV range.
Ultra Low Read Noise | 1.6e-Count Photons TE Cooling
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.The QHY2020 has dual stage TE cooling that reduces the sensor temperature to -40C below ambient.
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.
Electric Rolling Shutter | No Microlens High UV response
Microlens - free array, avoiding the influence on photometry and increasing the UV response.
High Frame Rate | 33 FPS USB3.0
The standard version of the QHY2020 is USB3.0. It can produce a maximum frame rate of 33 frames per second for single channel 12bit images, or 21.5 frames per second for dual channel 12-bit images (HDR mode). The camera can also transfer selected regions of interest for extremely fast rates, e.g., 450 FPS at 128lines, 1460 FPS at 32 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.
