€ 66,800.00 Price excl. German VAT tax (19%): € 56,134.45

  • World’s highest resolution cooled scientific CMOS Camera uses a 151 Megapixel Sony IMX411 Back-Illuminated Sensor - 14192 x 10640 pixel array with 3.76μm pixels
  • Native 16-bit AD on-chip – The output is real 16-bits with 65536 levels
  • Full Well Capacity of 44ke- at 3.76μm, 396ke- at 11um
  • Ultra-Low Read Noise, 1 Electron at High Gain, 2.4e- to 2.8e- at Low Gain
  • With extremely low dark current
  • Use SONY's Exmor BSI CMOS technology and Electronic Rolling Shutter
  • Air and Water Cooling with Two-stage Thermoelectric Cooler
  • Interfaces: USB 3.0 plus 2 x 10 Gigabit fiber. This camera model supports 2X10GB Ethernet ! An OPTIONAL QHY PCIE Kit (#1931116 , € 3050,-) is necessary to achieve such high transfer rates. HOWEVER - a grabber card is not necessary to operate the camera, since it is likewise capable to work under USB3.0 connection. Some users may own two or more ethernet compatible cameras but only do operate one camera at a time. In this case just one grabber card needs to be ordered. But for multiple cameras, each to operate with 2X10GB simultaneously, then the same number of grabber cards are needed.
  • Available in monochrome or color version

QHY411 M/C BSI Cooled Scientific Cameras

World's Largest Resolution, 151 Megapixels
The QHY411 is the highest resolution cooled scientific CMOS camera in the world. The 151 Megapixel SONY IMX411 back-illuminated sensor has a 14192 x 10640 pixel array with 3.76μm pixels. The sensor size is 54mm x 40mm. The QHY411 is available in both monochrome and color versions.

Native 16-bit A/D, 65536 levels
The 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, 2.4e- to 2.8e- at Low Gain
The QHY411 has only one electron of read noise at high gain and 1FPS (16-bit), 2FPS (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. At low gain the read noise is still only 2.4e to 2.8e-.

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 3.76μm 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.

USB3.0 / 2 x 10Gigabit Fiber
The QHY411 interface has a USB3.0 and  2 x 10Gigabit Fiber port. USB3.0 supports 2 FPS readout speed at 8-bits, 1 FPS at 16-bits and short bursts of 2 FPS at 16-bits. 10Gigabit supports 2.6 FPS at 16-bits continuous. For the use of the GB interfaces a QHY PCIE Kit (#1931116 , € 3050,-) is necessary to achieve such high transfer rates. The PCIE Grabbercard is required optionally and separately at extra charge. HOWEVER - a grabber card is not necessary to operate the camera, since it is likewise capable to work under USB3.0 connection. Some users may own two or more ethernet compatible cameras but only do operate one camera at a time. In this case just one grabber card needs to be ordered. But for multiple cameras, each to operate with 2X10GB simultaneously, then the same number of grabber cards are needed.

Air / Liquid Cooling
The QHY411 has 2-stage TE cooling that will cool to -30C below ambient with air (fan) only, or -45C below ambient with water circulation.

QHY411 Performance Curves

As a scientific camera, the QHY411 allows the user access to the various readout modes of the sensor in order to provide the maximum flexibility and usability of the camera in a wide variety of imaging applications. Currently there are 8 readout modes (more may be activated in the future). Different readout modes result in different behavior in full well, read noise and some other conditions.  The eight readout modes are mode #0 to mode #7. The following graphs show the system gain, read noise and full well capacity of each these 8 modes.
