QHY600C BSI Cooled Cameras

High Resolution, 61 Megapixels, Full Frame

The QHY600 uses the new Sony Full Frame (35mm format) IMX455 Back-Illuminated CMOS Sensor. It is available in both a monochrome version and a color version. The IMX455 is a 61 Megapixel, scientific CMOS sensor with 3.76um square pixels and 16-bit ADC. The sensor size is 36mm x 24mm.

Full Well Capacity, >51ke- at 3.76um, >400ke- Binned and up to >720ke- in Extended Mode

One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. Even with unbinned 3.76um pixels the QHY600 has a full well capacity >51ke-. When binned 2x2 to 7.5um the full well is >204ke- and when binned 3x3 to 11um the full well is >408ke-. In extended mode the full well is >80ke- unbinned, >320ke- binned 2x2 and >720ke- binned 3x3.

Native 16-bit ADC

With native 16-bit A/D on-chip, the output is real 16-bits with 65536 levels. A 16-bit ADC has a higher sample resolution than 12-bit or 14-bit ADC and the system gain will be less than 1e-/ADU. The QHY600 uses software digital binning. With digital summing, 2x2 binning will be four 16-bit summed = 18-bits.

Breakthrough Low Read Noise 1e- to 3.7e-

The QHY600 is capable of only one electron of read noise at high gain and 2 FPS 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.

Back-Illuminated, >87% QE, Low Dark Current

Sony's Exmor R back-illuminated technology produces sensors that Sony estimates are twice as sensitive as similar front illuminated sensors. QHYCCD tests have borne out this claim and based on our tests the peak QE is greater than 87%. Additionally, Sony sensors are well known for their low dark current. QHYCCD's proprietary thermal noise reduction technology and the QHY600's dual-stage regulated thermoelectric cooling further reduce dark current to extremely low levels, 0.0032e-/p/s at -20C for clean, long duration exposures.

Best Match for RASA System

The round camera case design of QHY600 and the high resolution, large area, small pixel array is an ideal match for RASA optical systems.

Photographic, Professional Models and Early Bird Version

Choose between three models:

  • The Photographic Model QHY600 PHOTO or the Professional Model QHY600 PRO. Each model is available in monochrome or color. Image quality is identical between the two models, however the Professional Model with the longer body has additional features.
  • Early Bird version of the camera has the hardware design of the Professional model, but the functions of the Photographic version. The Professional features can be enabled in a future upgrade for the difference in price. The amateur photography version have no chance to upgrade into profesional version.
Photographic Model QHY600 PHOTO: Professional Model QHY600 PRO:
  • USB3.0
  • 2.5 FPS, full frame, 16-bit images
  • 4.0 FPS, full frame, 8-bit image
  • Support for ROI at higher frame rates
  • USB3.0 
  • 2×10Gigabit optical fiber interface*
  • Programmable trigger in/out
  • Advanced timing interface for GPS
  • 4.0 FPS, full frame, 16-bit images
  • 10 FPS, full frame, 14-bit images 
  • 30 FPS 8K video
  • Support for ROI at higher frame rates
  • Customizable FPGA

* Requires optional PCIe card from QHYCCD.

Two 5m double optical fiber cables and two optical fiber modules are included with the camera.

The Professional version is more expensive than Photographic version and has a longer body to accommodate the length of the optical fiber interface.

The Early Bird version of the camera has the hardware design of the Professional model, but the functions of the Photographic version.  For example, the Early Bird version will have sockets for both Ethernet and USB3.0 but only the USB socket is active.  User who buy the Early Bird version can upgrade it to the full Professional version QHY600 PRO by paying the difference in price. (The amateur photography version have no chance to upgrade into profesional version) The Early Bird version also includes a free set of the QHYCCD 0.5mm-27.5mm spacers for precise and solid back-focus adjustment in a variety of optical train configurations.

An extremely inexpensive possibility to upgrade to a fiber optic camera at any time. This allows SCIENTIFICALLY correct operation and participation in observation programs that require 10 times the data speed and exact millisecond timing of many data streams from around the world.

The QHY600 Early Bird Price will end when the Photographic model is released or when the Early Bird inventory is exhausted.

Readout Mode Selection is a new function for the QHY600 and other newer QHYCCD cameras. Different readout modes have different driver timing, etc., that cause the sensor to yield different performance results, allowing you to tailor the sensor response to your particular imaging needs. Each readout mode has its advantages and disadvantages. The QHY600 currently has three readout modes. In the future QHYCCD may add more modes.

Readout Mode #0 (Photographic Mode). In this mode, the read noise of the QHY600 drops between a gain setting of 25 and 26. We therefore recommend setting the gain to 26 as a starting point. At gain=26, the full well is 27ke- and read noise is 2.7e-. For long exposures where read noise performance is not as critical, lowering the gain results in higher full well.

QHY600 Dynamic Range (Photographic Mode)

Readout Mode #1 (High Gain Mode). In this mode, the QHY600 switches from Low Gain to High Gain between gain settings of 55 and 56. Gain 0-55 uses LGC and Gain 55-100 used HGC.

Readout Mode #2 (Extended Full Well Mode). In this Ultra-High Full Well Mode, the QHY600 exhibits an unbinned full well capacity of greater than 80,000e-. Binned 2x2 the full well is greater than 320,000e- and binned 3x3 the full well is greater than 720,000e-.

QUANTUM EFFICIENCY AND DARK CURRENT TEST RESULTS

Quantum Efficiency.
Sony provides a relative QE curve for the IMX455 sensor. in order to determine the absolute QE of this curve QHYCCD ran tests comparing the response of the IMX455 sensor against a camera of known absolute QE at two wavelengths along this curve (489nm and 656nm). From these test results we can plot a good estimate of the QHY600 QE curve in absolute terms with a peak QE >87%:

QE QHY600

Dark Current.
Dark current results for the QHY600 are based on measurements of the dark current of the IMX455 sensor installed in the QHY600 camera. At 0C the dark current is 0.014e-/p/s and at -20C it is 0.003e-/p/s:
