QHY461 M/C BSI Cooled Scientific Cameras

High Resolution Scientific CMOS with 102 Megapixels
The QHY461 uses a Sony IXM461 Exmore R scientific CMOS sensor with similar architecture as the larger IMX411.  The QHY461 has 102 Megapixels in a 11656 x 8742 array with 3.76um pixels.  The IMX461 is back-illuminated for high QE and dynamic range.  The sensor size is 44mm x 33mm, 55mm diagonal.  The QHY461 is available in both mono and color versions.

Native 16-bit A/D, 65536 levels
The QHY461 and QHY411 is also the world's first scientific CMOS camera with native 16-bit A/D on-chip.  The output is real 16-bits with 65536 levels. Most CMOS sensors are 12-bit or 14-bit. This means that the conversion ratio cannot achieve 1e-/ADU and weak signals are not very highly sampled.  Photometric measurements of low signals in such case are not as accurate.  Some cameras combine two 12-bit outputs to create 16-bit images, but the actual number of levels is still 4096 x 2 = 8192 levels, significantly less than native 16-bits.

Ultra Low Read Noise, 1 Electron at High Gain
The QHY411 has only one electron of read noise at high gain and 1 FPS (16-bit), 2 FPS (8-bit) high readout speed. One electron of read noise means the camera can achieve a SNR>3 at only 3 to 4 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys and time domain astronomy.

Full Well Capacity of 44ke- at 3.76um, 396ke- at 11um
One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. The QHY411 has a full well capacity of 44ke- even with unbinned 3.76um pixels.  When binned 2x2 to 7.5um the full well is 176ke- and when binned 3x3 to 11um the full well is 396ke-.

Back-Illuminated, Electric Rolling Shutter, Low Dark Current
The QHY411 sensor is back-illuminated and has extremely low dark current using SONY's Exmor BSI sCMOS technology. This means the camera is not only ideal for short exposures due to its low read noise, but is also ideal for long exposures where dark current noise often dominates.  Top further reduce the dark current noise, the QHY411 incorporated QHYCCD's proprietary thermal noise reduction technology and two-stage thermoelectric cooling to reduce the temperature of the sensor.

10GigaE / USB3.0
The QHY461 comes in two versions, USB3.0 and 10GigaE. The USB3.0 supports 1FPS readout speed. The 10GigaE version supports 2.6FPS readout speed.

Air / Liquid Cooling
The QHY461 has air or liquid cooling with 2-stage TE Cooler.
