Like many modern scanners, the illumination source is a strip of white LEDs, which is virtually instant-on and doesn’t have the warm-up time of a cold cathode tube. Traditionally, CCDs have been thought to render images better and certainly to have a greater depth of field, being suitable for scanning some 3D objects, like jewellery, as well as 2D pages and pictures. There are still plenty of situations, though, where the greater quality attained from a dedicated scanner is worth paying a little extra for, and Epson’s Perfection V37 (also available as the V370 with added transparency scanner) comes into its own.Įpson is a major manufacturer of flatbed scanners and the Perfection V37 is an interesting unit, as it uses a Charge Coupled Device (CCD) rather than a Contact Image Sensor (CIS) to gather reflected light from the document or photo and form an image from it. The market for standalone scanners isn’t what it once was, which is primarily down the fact that all-in-one printers have taken away much of the demand thanks to their added convenience.
