QHYCCD QHY600 Monochrome CMOS Camera - Short Back Focus Version
QHYCCD QHY600 Monochrome CMOS Camera - Short Back Focus Version
QHY has designed the US version of the short back focal length (SBFL) camera for users of a Canon or Nikon lens with an attached filter wheel. It is advised that customers who do not need the short backfocus, do not purchase this version of the QHY600 camera. The structure of the camera puts the optical glass close to the sensor, increasing the chance of dew formation.
QHY600 cameras are full frame astrophotography cameras with extremely low dark and read noise that utilizes the 36mm x 24mm Sony IMX455 back-illuminated, full frame sensor with 3.76um pixels. The back-illuminated CMOS structure provides this camera with improved full well capacity.
When unbinned, the camera has a full well capacity of more than 51ke-. When binned 2x2 to 7.5um, the camera's full well is 196ke-. Additionally, when binned 3x3 to 11um, the full well is 441ke-. Not only does this camera already have an impressive 51ke- full well capacity, but QHY has implemented a way to achieve a higher full well capacity with user controlled read modes. There is extended full well readout mode, meaning the QHY600 can achieve a greater full well of more than 80ke-. This gives a better dynamic range and large variations in magnitude of brightness are less likely to saturate. There are three readout modes, each with their own characteristics.
QHY600 Camera Features You'll Love
Round Body Design : The round camera design of this camera makes it ideal for the new generation of RASA telescopes because it can match the image field.
Electric Shutter : Equipped with an electronic rolling shutter, the camera utilizes Sony's Exmor BSI CMOS technology and electric shutter. This type of shutter is more reliable than a mechanical shutter and more stable when the astrophotographer takes a large number of exposures.
Low Read Noise : The QHY600 has only one electron of read noise, meaning the camera can achieve an SNR>3 at only four to six photons. You can use this camera for short exposures, narrow band imaging, sky surveys, time domain astronomy, fluorescence imaging, DNA sequencing, and microscopy! QHY has added an innovative suppression technology that can reduce the level of random noise such as the the type of thermal noise that is generated by back-illuminated CMOS sensors and has a value not related to the exposure time.
The high pixel count of this CMOS camera means that the memory requirements for temporary and permanent storage is greater. The QHY600 sensor produces about 120MB of data per frame. Additionally, the data band-width is increases from 16-bits to 32-bits. To sufficiently meet the memory needs, the QHY600 comes with large-capacity memory of up to 1GB.
Native 16-bit A/D : The native 16-bit A/D on-chip of this camera has an output of 65536 levels. This means that the camera gives a higher resolution and a system gain that is less than 1e-/ADU. QHY's 600 series camera has no sample error noise and very low read noise.
2GB Image Buffer : The QHY600 comes with a 2GB DDR3 image buffer for smooth, uninterrupted, and high-speed data transfer.
USB3.0 : QHY's design allows the camera to support USB3.0 high speed interface.
QHY's incorporated USB re-connection feature means that this camera's computer connection can be connected and disconnected by turning the 12V power supply on and off. This means you do not have to worry about plugging and unplugging the USB cable, enhancing user control when working from a remote station. All you have to do is control the 12V power supply to control the remote USB connection.
Application : This camera is great for astro-imaging, all sky meteor monitoring, microscopy, fluorescence imaging, high throughput DNA sequencing, aerial photogrammetry.
Updated Body Design!
The QHY600M now comes with an elevated heating board. QHY has raised the board by 5mm. This decreases the likelihood of fogging, but does not change Back focus length calculations or any other function. While the above images currently show the regressed heating board, to the left is a visual aid to show this update. The picture shows the QHY268 Monochrome camera but is still a good illustration of the change. Please Note: This change is still being rolled out by the manufacturer, so we cannot guarantee which version of the body design you will receive. If you have any questions or concerns, please don't hesitate to call us at 1-800-266-9590 or send an email, and we will be happy to help you. Thank you!
