The Gel Logic camera utilizes a “Scientific Grade CCD.” What does this mean and why is it important?
Manufacturers grade CCD sensors according to the number and type of pixel defects present. Defects, also known as “hot pixels” are pixels that do not accurately represent true signal level. To provide insight into the number of pixel defects on a given CCD, manufacturers have designated a grading scheme where a grade 0 CCD is the highest quality (least amount of pixel defects), and grades 1, 2, and 3 represent CCD’s with increasing amounts of pixel defects. The Gel Logic camera’s scientific grade 0 CCD provides confidence that your analysis data is based on actual sample data and has not been adversely affected by pixel defects. Many CCD’s manufactured for consumer level digital cameras are not graded and do not have to meet these stringent quality standards, since they are designed for point and shoot photography.
