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.\u003c\/p\u003e\n\u003cp\u003eIn 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 \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602542.png\" class=\"oceanwp-lightbox\"\u003e\u003cimg loading=\"lazy\" decoding=\"async\" alt=\"\" width=\"100\" height=\"100\" data-src=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602542.png\" class=\"wp-image-1573 alignleft ls-is-cached lazyloaded\" src=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602542.png\"\u003e\u003c\/a\u003e\u003cstrong\u003eTRUE RAW Data\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\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 \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602234.png\" class=\"oceanwp-lightbox\"\u003e\u003cimg loading=\"lazy\" decoding=\"async\" alt=\"\" width=\"100\" height=\"100\" data-src=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602234.png\" class=\"wp-image-1604 alignleft ls-is-cached lazyloaded\" src=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602234.png\"\u003e\u003c\/a\u003e\u003cstrong\u003eAnti-Dew Technology\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBased on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions.
