Improtant note: Many of the QHY4040 PRO camera models with two 10 Gigabit fiber interface are available in special scientific or commercial versions, such as liquid cooling, which require an optional PCIE Crabber Card to be ordered separately. For orders of such special versions or for other special project requirements, please contact us by email to discuss your requirements and find the best solution. All QHY models can be found on our QHY price list.

Cooled scientific camera uses the Gsense4040FSI Front-Side-Illuminated (FSI) or Back-Side-illuminated (BSI), 16.8 Megapixel, CMOS image sensor – 36.9mm x 36.9mm square sensor with 9.0um pixels in a 4k x 4k array
Multiple Pixel Clocks, 20 FPS at Full Resolution
Quantum efficiency of FSI sensor (Standard and Pro version) of 74% at 600nm, ultra high dynamic range of 86dB, extremely low readout noise of 4e-,Quantum efficiency of BSI sensor (Pro version) of 90% at only 2.3e-
With Electronic Rolling Shutter and Two-stage Thermoelectric Cooling (-35 °C below ambient)
Ideal for astronomical, biological, X-ray imaging
More technical data in the table below
The QHY4040 is available in two versions:

QHY4040 Standard with FSI sensor with built-in 128MB DDR3 memory and USB3.0 interface
QHY4040PRO FSI or BSI sensor with bulit-in 2GByte DDR3 memory, USB3.0 interface and 2x10 Gigabit Fiber port. The PRO camera models support 2X10GB Ethernet (An OPTIONAL QHY PCIE Kit (#1931116 , € 3205) is necessary to achieve such high transfer rates). HOWEVER - a grabber card is not entirely necessary to operate the camera, since it is likewise capable to work under USB3.0 connection. 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.

Important note: The scientific CMOS cameras of QHYCCD are not in stock and can be ordered from the manufacturer on request. Please contact us in advance by email if you would like to place an order

Description

Details

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 QHY PCIE Kit (#1931116 , € 3205) 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.
