QHY4040 FSI / BSI Cooled Scientific Cameras (CMT, CMN)
Large Area Sensor, 36.9 x 36.9mm 4K x 4K
The QHY4040 models are scientific cooled CMOS cameras with GSENSE4040 sCMOS sensor. It has a 36.9mm x 36.9mm square sensor with 9.0um pixels in a 4k x 4k array. It has a 36.9*36.9mm big image area. 9um pixel size.
In addition to the standard USB 3.0 interface, the two PRO versions each have 2 x 10 GB Ethernet fiber optic interfaces for faster data transfer (or for longer distances between PC and telescope). For the use of the GB interfaces, a PCIE Crabber Card (#1931167, € 1275,-) is required optionally and separately at extra charge. Some users may own two or more ethernet compatible cameras but only do operate one camera at a time. In this case just one grabber card needs to be ordered. But for multiple cameras, each to operate with 2X10GB simultaneously, then the same number of grabber cards are needed.
Multiple Pixel Clocks, 20 FPS at Full Resolution
The QHY4040 has a USB3.0 high-speed interface with up to 5GB of bandwidth. The camera achieves 1:1 video output at 20 frames per second (8-bit) with 4096 x 4096 resolution or 8FPS in low noise 12-bit mode. As different clock rates affect read noise performance, the QHY4040 supports five readout clocks and 8FPS, 12FPS, 16FPS, 18FPS and 20FPS frame rates.The QHY4040PRO (available in either FSI or BSI versions) supports selectable dual 12bit channel output (high gain, or low gain), and also supports the on-camera dual 12bit to 16bit data combination process.
Front-Side-Illuminated, 74% QE, 86dB Dynamic Range, 3.7e- Read Noise (standard version)
The QHY4040 version with FSI sensor has an ultra-high dynamic range of 86dB and an extremely low readout noise of 3.7e-. This makes the camera exceptional for astronomical imaging, medical imaging, life sciences, fluorescence detection, trace sciences.PRO version: available with Front-Side Illuminated & Back-Side Illuninated sensors
QHY4040/PRO has both the FSI version and BSI version. FSI version has a peak QE of 74%, 70ke full-well (at the lowest gain), 4e readout noise (at the highest gain). BSI version has a peak QE of 90%, 39ke full-well (at the lowest gain), 2.3e readout noise(at the highest gain), and a wide spectrum from UV to Near IR.Dual Stage Regulated TE Coolling -35C
The QHY4040 has 2-stage thermoelectric cooling that reduces the sensor temperature to -35 °C below ambient. TE cooling significantly reduces dark current and produces cleaner, lower noise images over long exposures. The PRO versions are also available with liquid cooling for an additional charge. It lowers the sensor temperature down to - 40 degrees below ambient temperature.Astronomical Imaging, Biological Imaging, X-Ray Imaging, Dynamic DR
The high sensitivity, large field of view, 9um pixel size and large dynamic range are all ideal for astronomical imaging with long telescope focal lengths. . The large 36.9mm x 36.9mm sensor with high resolution, high quality Image output also makes the QHY4040 ideal for Biological imaging. For dynamic medical x-ray DR imaging the QHY4040 sensor size matches most industry-standard DR lenses and the high frame rate and low readout noise performance is ideal for X-ray imaging.The QHY4040 is available in two version:

*For the use of the GB interfaces, a PCIE Crabber Card (#1931167, € 1275,-) is required optionally and separately at extra cost. If several cameras are to be operated in parallel via the fiber optic interface, the same number of PCIE boards is required. An interface board is NOT required if the camera is only operated via the standard USB 3.0 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....
