Grading Scientific CCD Sensors; Considerations to be Made Pre-Purchase

The cost of a CCD (charge-coupled device) sensor is a primary determinant of the overall cost of a CCD camera system. The cost of sensors can be influenced by a number of factors, such as production volume, device configuration, pixel format, coatings, and grade. Prospective buyers should get detailed sensor-grade, cost-issue information directly from the camera-system manufacturers. This application note by Photometric presents a range of considerations to be made before purchasing CCD camera systems, particularly focussed on Scientific CCD sensor grading.
