QHY367C Cooled CMOS camera 36MP

QHY367C is the flagship model of the QHYCCD Medium COLDMOS series, offering 36 megapixels on a full frame size colour CMOS sensor. 4.88µm pixel size and 14 bit ADC.

Notable features include 128MB DDR-II image buffer and 35ºC delta cooling capability with full anti-dew solution.

Ultra-High Performance

QHY367C is equipped with a full frame 36mega pixels, 14bit CMOS sensor sony IMX094. Readout noise is only 3.2e- at lowest gain and 2.4e- at unity gain (system gain = 1e-/ADU). QHY367C has a vast dynamic range of more than 14 STOPs.

True RAW Image Output

QHY367C has the same CMOS sensor as used on D800/810A. Although DSLR has RAW image output but typically it is not truly raw. You will find the de-noise signature on the raw images from the hot pixel patterns. The QHY367C offers the TRUE RAW image output and it offers completely original signal and retains the maximum flexibility for astronomy image processing.

Unique Thermal Noise Reduction Technology

Besides the 2-stage TEC, QHYCCD has a unique thermal noise control technology which results in very low thermal noise and empower the whole 165/168/247/367 product line to have much better thermal noise performance than any other similar offerings. 

128MB DDR-II Image Buffer

QHY367C has 128MB DDR-II image buffer to serve as image cache to avoid the risk of losing frame. The data is stored in the DDR first and then transferred to computer. This avoids the USB port from being too busy when there is more a USB3.0 camera or other devices connected. The generous buffer helps facilitating large image transfer, preventing frame lost after long exposure during transfer and allows the camera to run smoothly when used with low performance computer or USB2.0 port.

Anti-Dew Technology

With her long history and professional experience in cooled CCD camera design, QHYCCD designs its camera with comprehensive anti-dew technology for both CCD sensor surface glass and the optics window glass.

The QHY367C has an electric heating board surrounding the CMOS glass window, preventing dew from forming. A silicone gel tube socket is in place for controlling the humidity within the air proof CMOS chamber if necessary.

With these technologies you do not need to worry about the dew formed on both CMOS sensor and the optics window, even in a high humidity environment.

AR+AR optics window

To avoid halos to form around the bright star due to internal reflections, the QHY367C has a double layer AR+AR coated optics window instead of the common IR cut window as used on OSC (one-shot colour) cameras. We advise astrophotographers to use an IR-cut filter in front of the camera. A 2 inch filter holder is available for installing this IR-cut filter.
