QHY 42 Scientific CMOS Series
The QHY42-BSI is a cooled scientific CMOS camera with extremely low (1.6e-) read noise and a backside illuminated CMOS sensor with 95% peak QE. We also offer the QHY42-BSI in a UV enhanced version as well as a front illuminated version.
The low read noise and high QE make it possible to achieve high SNR even when imaging dim objects. Only 5 photons produce a SNR>3.
The sensor array is 2048 x 2048 with relatively large 11um pixels and 89ke- full well capacity. The sensor size is 22.5mm x 22.5mm yielding a good field of view even at longer focal lengths. The QHY42-BSI 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-BSI is ideally suited to scientific research, astronomy, biology, UV and low light imaging.
There are three types of the sensor: TVBIS, UV, VIS (Front-Illuminated). The TVBIS is the most popular type and it has the best QE of 95%. The UV version has a peak QE of 76% on the 275nm. While the TVBIS version has also a high UV QE at 240nm. Both TVISB and UV is possible for UV use. You can select it according the QE curve. And the TVISB version has lower dark current than UV version. VIS version is not so popular and sometimes the sensor factory does no stock.
The first version QHY42 is released in early 2018. And now QHYCCD has released the enhanced version QHY42PRO. The different of QHY42 and QHY42PRO is that QHY42 only support the single ADC channel output (which called STD mode in the datasheet of Gsense400 , and 24FPS for 8bit/12bit . While the QHY42PRO support both STD mode and the dual channel ADC mode (HDR mode). The dual ADC can work together to sample the same pixels. And output two images. One is high gain and another is low gain. Which can enlarge the dynamic of the output data. The QH42PRO HDR mode will output the 4096*2048 image. Which consist two 2048*2048 image. QHY42PRO also support the remote FPGA upgrade function via USB port.

Important System Driver Update Information - For All QHYCCD Cameras
Breaking news from QHYCCD: QHY - Important firmware driver upgrade 9/21 Based on an update notification of the USB chip, we added a new API in the firmware of all QHYCCD cameras between 2021.7.10 and 2021.9.4. According to the description, we were expecting that this modification would increase the stability of the USB link. Unfortunately, however, we have received feedback from our users that it can cause a random crash in single frame capture mode on some computers. These random events can occur after some minutes or some hours or even longer time frames. To test these reports, we changed back to the system driver release before 2021.7 and have confirmed that without this new API the random crashes disappear. In order to avoid this problem, we urgently released versions 2021.9.10 and 2021.9.18 without the new API and the random crashes do not occur. The difference between versions 2021.9.10 and 2021.9.18 is that version 2021.9.18 has an improved UVLO (under-voltage lock out) detection function to help avoid a false detection of an under-voltage event. Therefore, if you installed the system driver or the All-in-One Installer between 2021.7.10 and 2021.9.4, we strongly recommend that you update the drivers by installing the...

QHY HISTORY
QHYCCD Cameras – Discover New Horizons COMING SOON COMING SOONCOMING SOONCOMING SOON From childhood Dr. Qiu Hongyun held a keen interest in nature, science and technology. As a young boy he would go to the chemical factory where his father worked and do chemistry experiments in the lab. He also enjoyed tinkering with electronics and made small board projects and a radio. In the 5th grade he read in a Science magazine about the approach of a comet. He tried to see the comet and although the toy binoculars he was able to find failed to be useful in spotting the comet, the effort and excitement of the event generated an interest in astronomy and that interest led to his making a small refractor telescope and later to attempt astrophotography with film. He had no camera only a homemade film holder. He would develop the film himself. By the time he was in Middle School, his interest in astronomy had grown. As a science project, he made an ultra-long zoom lens (about 800-3000mm) and got very good results with it. The lens earned him an award for invention and even an award for innovation his first year of University study....
