E.d.i.t
From Wikipedia, the free encyclopedia
E.D.I.T is Emulsion Direct Imaging Technology™ that is used on Microtek’s dual-platen scanners. E.D.I.T. utilizes a glassless internal scanning bed to precisely capture transparent media directly from the emulsion surface. This design eliminates refracted light, allowing the CCD to reproduce realistic images free from Newton Rings, distortion and other unwanted artifacts. The CCD sensor is now able to render the full dynamic range from the image and provide optimal results with sharp details and accurate color readings. As in drum scanning, E.D.I.T. technology enables a scanner CCD lens to read directly from the emulsion side of the film without any glass between the lens and the scanned target. This eliminates any possible distortion and so-called Newton Rings caused by the glass. By adopting E.D.I.T., the CCD sensor is able to capture the most realistic image without distortion, render the full dynamic range from the image, and provide the optimal results with sharp details. The switching flip-mirror and removable film holder design are the two most important factors of E.D.I.T. At first glance, a scanner with E.D.I.T. design does not differ a lot from regular scanners. A glass surface will be seen after lifting the upper cover, which is the location for placing reflective materials, and there is a drawer-like, removable tray under the glass surface. After pulling out the tray, the film holder will depart from the tray in order to exchange different holders. There are various holders for 4 x 5", 6 x 9 cm, 35 mm slide, and 35 mm film strip. These film holders are designed to make it easy to align the films, and ensure the film is kept flat and stretched out. There are two unique design concepts in the optical system behind E.D.I.T.: Dedicated light source for reflective and transparent media. The film holder tray is installed inside the scanner and, at the same time, there is an extra light source installed specifically for transparent media below. There is another light source installed above the holder for reflective materials, so light for the transparent media does not have to travel through any glass. The flip-mirror design allows a flexible light path depending on the scanned media by switching mirrors according to the scan mode setting. Both transmissive and reflective scanning are possible in one mechanical layout.
