A monochrome, back-illuminated, high-sensitivity, astronomical imaging camera is the ideal choice for astro-imagers. The QHY600 uses the latest SONY back-illuminated sensor, the IMX455, a full frame (35mm format) sensor with 3.76um pixels and native 16-bit A\/D.  This sensor is available in both monochrome and color versions.  The QHY600 ends the days of non-16bit CMOS cameras and it ends the days non-full frame (and larger) monochrome CMOS cameras.\u003c\/p\u003e\n\u003cp\u003eThe QHY600 has extremely low dark current (0.002e\/p\/s@-20C) using SONY’s Exmor BSI CMOS technology. QHY600 is also a zero amplifer glow camera. The QHY600 has only one electron of read noise at high gain and full resolution and 4FPS readout speed.  One electron of read noise means the camera can achieve a SNR\u0026gt;3 at only 4 to 6 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, time domain astronomy, fluorescence imaging, DNA sequencing and microscopy.\u003c\/p\u003e\n\u003cp\u003e\u003ca class=\"oceanwp-lightbox\" href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210421380-scaled.jpg\"\u003e\u003cimg class=\"wp-image-298 aligncenter lazyloaded\" src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-scaled.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1\" sizes=\"(max-width: 500px) 100vw, 500px\" srcset=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-scaled.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 2560w, https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-768x512.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 768w, https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-1536x1024.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 1536w, https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-2048x1365.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 2048w\" alt=\"QHY600 Astronomy Camera: Sony IMX455 CMOS, Full Format, BSI, 3.76um Pixels, Native 16bit A\/D, 60MP, 2GB DDR3, Mutiple Readout Modes\" width=\"500\" height=\"333\" data-srcset=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-scaled.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 2560w, https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-768x512.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 768w, https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-1536x1024.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 1536w, https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-2048x1365.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1 2048w\" data-src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210421380-scaled.jpg?lossy=1\u0026amp;strip=1\u0026amp;webp=1\" data-sizes=\"(max-width: 500px) 100vw, 500px\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQHY600PH-SBFL (Short back-focal length version)\u003c\/strong\u003e\u003cspan\u003e ：specially designed for DSLR lens users or those who has special requirment of short back focal length.

This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor. In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.\u003c\/p\u003e\n\u003cp\u003e\u003ca class=\"oceanwp-lightbox\" href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602540.png\"\u003e\u003cimg class=\"alignleft wp-image-1583 lazyloaded\" src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210602540.png?lossy=1\u0026amp;strip=1\u0026amp;webp=1\" alt=\"\" width=\"50\" height=\"50\" data-src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210602540.png?lossy=1\u0026amp;strip=1\u0026amp;webp=1\"\u003e\u003c\/a\u003e\u003cstrong\u003eZero Amplify Glow:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eThis is also a zero amplifer glow camera.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca class=\"oceanwp-lightbox\" href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602542.png\"\u003e\u003cimg class=\"alignleft wp-image-1573 lazyloaded\" src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210602542.png?lossy=1\u0026amp;strip=1\u0026amp;webp=1\" alt=\"\" width=\"50\" height=\"50\" data-src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210602542.png?lossy=1\u0026amp;strip=1\u0026amp;webp=1\"\u003e\u003c\/a\u003e\u003cstrong\u003eTRUE RAW Data:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eIn the DSLR implementation there is a RAW image output, but typically it is not completely RAW.  Some evidence of noise reduction and hot pixel removal is still visible on close inspection.  This can have a negative effect on the image for astronomy such as the “star eater” effect.  However,  QHY Cameras offer TRUE RAW IMAGE OUTPUT and produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.\u003c\/p\u003e\n\u003cp\u003e\u003ca class=\"oceanwp-lightbox\" href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602234.png\"\u003e\u003cimg class=\"alignleft wp-image-1604 lazyloaded\" src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210602234.png?lossy=1\u0026amp;strip=1\u0026amp;webp=1\" alt=\"\" width=\"50\" height=\"50\" data-src=\"https:\/\/b2863465.smushcdn.com\/2863465\/wp-content\/uploads\/20210602234.png?lossy=1\u0026amp;strip=1\u0026amp;webp=1\"\u003e\u003c\/a\u003e\u003cstrong\u003eAnti-Dew Technology:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eBased on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions.

Nevertheless, QHYCCD has implemented a unique approach to achieve a full well capacity higher than 51ke- through innovative user controllable read mode settings. In Extended Fullwell Mode, the QHY600 can achieve an extremely large full-well charge value of nearly 80ke- and the QHY268 can achieve nearly 75ke-. Greater full-well capacity provides greater dynamic range and large variations in magnitude of brightness are less likely to saturate. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMode-2CMS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBased on the three basic modes above, 2CMS mode can greatly reduce readout noise by secondary sampling while keeping the same full well value and system gain.
