CIS devices typically produce lower image quality compared to CCD devices; in particular, the depth of field is greatly limited, which poses a problem for material that is not perfectly flat. However, a CIS contact sensor is smaller and lighter than a CCD line sensor, and allows all the necessary optical elements to be included in a compact ...

Scanner unit with CIS. A: assembled, B: disassembled; 1: housing, 2: light conductor, 3: lenses, 4: chip with two RGB-LEDs, 5: CIS. Scanners equipped with contact image sensor (CIS) scanning elements are designed to be in near-direct contact with the document to be scanned and thus do not require the complex optics of CCDs scanners. However ...

Configuration items are represented by their properties. These properties can be common to all the configuration items (e.g. unique item code that we will generate, description of function, end of the lifecycle or business owner that is approving configuration item changes and technical owner, i.e. administrator, that is supporting it and implementing the changes).
With sCMOS, digital information for each frame is generated rapidly and with an improved low-light image quality. The sCMOS sensor's low read noise and larger area provides a low-noise, large field-of-view (FOV) image that enables researchers to scan across a sample and capture high-quality images. [9] [5]
