- Color astronomy camera with Sony IMX294 back-illuminated 11.7-Megapixel CMOS sensor with 4164x2796 pixel array
- Ultra-low dark current and readout noise
- Two-stage cooling keeps sensor temperature as much as 35C below ambient for low-noise imaging, even in warm conditions
- 256MB DDRII data buffer to minimize frame loss dropouts during image transfer
- Anti-dew technology to minimize condensation on window in humid conditions
1. Back-Illuminated 4/3-Inch 11.7-Megapixel Sensor for High-Resolution Imaging and EAA
The new QHY294 Pro is a 4/3-inch back-illuminated camera, equipped with Sony IMX294 (Color) sensor. The 294 Pro has 11.7 MP at 4.63um, 14-bits A/D.
2. Expanded Pixel Mode 11.7MP to 46.8MP
The IMX294 chip has 46.8 million 2.315um pixels, which Sony 2x2 bins on-chip to create the sensor's advertised 11.7 million 4.63um pixel array. The QHY294 Pro series camera is capable of locking and unlocking the on-chip binning to provide two readout modes. The first mode reads the sensor "locked" mode to produce 11.6mp images with 4.63um pixel size and 14 bits per pixel. The second read mode unlocks the binning to produce 46.8mp images with 2.315um pixel size at 12 bits per pixel.
3. Low Readout Noise
Preliminary tests indicate that this sensor will be an outstanding performer with extraordinarily high QE, low read noise, and low dark current. The 294 has 6.8 to 6.9e- read noise at the lowest gain, 1.6e- read noise near unity gain, and 1.0e- read noise at highest gain, with great dynamic range! Pricing will be announced at a later date.
4. Dual Gain Auto Switch
HGC/LGC MODE Boosts Low Light Performance. The QHY294 Pro CMOS sensor has a dual gain mode, HGC (high gain) and LGC (Low gain). The QHY294 Pro 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.
5. Anti-Dew Technology
The QHY294 Pro 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.
6. 256MB DDR3 Image Buffer
The QHY294C has an internal 256MByte high speed DDR3 image buffer to protect against unexpected drops in data transmission. This is more than enough buffer for one frame and it significantly reduces any issue of lost frames due to a busy computer CPU or slow USB communication packet errors. The buffer also helps smooth video transfer when using a slow computer.
7. Flexible Adapters
The QHY294C-Pro 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.
Optional accessories:12V power adapter + power cable, C-adapter lens mount
If you wish to supply your own 12V power adapter, its output current must be at least 3.5A and the polarity must be center positive.
