Brand: QHYCCD / SKU: QHY-268M-PRO (110089)
Different from QHY268PH, the QHY268PRO is specially designed for scientific use with advanced qualities and functions. QHY268Pro M is a cooled scientific CMOS camera with a SONY IMX571 APS-C format CMOS sensor inside. 26mega pixels, back-illuminated, native 16BIT ADC. QE is up to 91% and readout noise is as low as 1.1e. Even with a 3.76um pixel size, it has a big full well up to 75ke.

Currently QHY offers a monochrome QHY268M Pro I as standard model. If you have requirement for a liquid-cooled version (QHY268M PRO LQ) or color version (QHY268C PRO), please contact us.

The QHY PCIE Card Kit is not included in QHY268M PRO; you can choose it in the add-ons below.

About This Product
The QHY-GPSBOX is a compact camera accessory that provides high-precision GPS hardware time scales allowing some QHYCCD cameras to obtain accurate time information of the camera's exposure time. In addition, this information is returned to the camera internally and added to the image data after the start of one frame of the image. GPS timing information and image information are therefore completely consistent. No confusion is created due to transmission, buffering or other reasons. It is very convenient to use and read.

QHY268 Pro M has a SONY IMX571 APS-C format CMOS sensor inside. 26mega pixels, back-illuminated, native 16BIT ADC. QE is up to 91% and readout noise is as low as 1.1e. Even with a 3.76um pixel size, it has a big full-well up to 75ke. It has extremely low thermal noise 0.0005e/pixel/sec @ -20C, ZERO amplifier-glow performance, It has a maximum frame rate of 6.8FPS@16bit full resolution. QHY268PRO has both a USB3.0 and 2*10Gbps optical fiber interface. It has a 2GBytes big DDR3 memory buffer. It has the 6pin GPIO port support complex Trig-In and Trig-Out signal. It can connect with QHY GPS-BOX to get a high-precision GPS timestamp onto the image head.

Native 16 bit A/D: The Sony sensor has native 16-bit A/D on-chip. The output is real 16-bits with 65536 levels. Compared to 12-bit and 14-bit A/D, a 16-bit A/D yields higher sample resolution and the system gain will be less than 1e-/ADU with no sample error noise and very low read noise.

BSI: One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor. In the back- illuminated sensor, the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer, and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency, the more efficient the sensor is at converting photons to electrons, and hence the more sensitive the sensor is to capturing an image of something dim.

Zero Amplify Glow: This is also a zero amplifier-glow camera.

True Raw Data: QHY Cameras offer true raw image output and produce an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.

Anti-Dew Technology: Based on almost 20-year cooled camera design experience, QHY cooled cameras have implemented a full dew control solution. The optic window has a built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with a silicon gel tube socket design for control of humidity within the sensor chamber.
