Short Description

The QHY294C uses a 4/3-inch back-illuminated cooled color CMOS sensor, 14-bit A/D. 6,8e readout noise in lowest gain, 1.6e- read noise near unity gain and 1e- read noise at highest gain. The QHY294C is a very good camera for you to begin your deep sky imaging. This camera is a dedicated cooled camera with high performance for both QE, dark current and readout noise.

Description

Details

4.6um
64ke- Full Well

Benefiting from the back-illuminated structure, the area around the photo-diode is reduced so that for a given pixel size the BSI sensor provides a greater full well capacity compared to a front illuminated sensor. The QHY294C has a full well capacity of nearly 65,000 eletrons with 4.63um x 4.63um pixels, almost the same as an interline CCD camera with 9um pixels.

16.5 FPS at Full Resolution, Higher Rates in ROI Mode

The QHY294C produces 16.5 high resolution frames per second, 11.6 Megapixels with 14-bit A/D. Higher rates are achieved in ROI mode, for example, 41 FPS at 1080 lines.

0.005e-/p/s @ -20C

The QHY294C uses QHYCCD's proprietary low dark current control technology. This technology significantly reduces the dark current noise in our CMOS cameras. The QHY294C has super low dark current as a result, lower than many CCD cameras, allowing for very long exposure times.

HGC/LGC MODE
Boosts Low Light Performance

The QHY294C's CMOS sensor has a dual gain mode, HGC (high gain) and LGC (Low gain). The QHY294C will switch the two modes automatically when the gain is set to 1600 you will get the benefits of the ultra low read noise (1e- to 1.6e-) of the HGC mode and a full well capacity of about 14.5ke- at the switch point setting.

Anti-Dew Technology

The QHY294C benefits from more than a decade of cooled camera design experience. QHYCCD has implemented full dew control solutions. The optical window has a built-in dew heater and the CMOS chamber is protected from internal humidity condensation.

Flexible Adapters

The QHY294C has the same body design and mechanical interface and the QHY163. It has a short back focal distance allowing the use of QHYCCD's 0.5mm-27mm spacers (step size 0.5mm) for flexibility in setting up your optical train.

256MB DDR3 Image Buffer

The QHY294C has an internal 256MByte high speed DDR3 image buffer. This is more than enough for one frame and it significantly reduces any issue of lost frames due to a busy computer CPU or slow USB communication packet errors.

*Note:QHYCCD has optimized the cmos drive freqency and limit the max frame rate. The CMOS sensor may not work under the maxium frequency to ensure the better noise performance. If you need the customized higher frame rate version please contact QHYCCD.
