Better Optics Arrive for Video Tubing Gauges.Telecentric optical lenses, which bring an image into focus without changing the size of the image, are now available for off-line video measuring instruments. Optical Gaging Products Inc., a Rochester Rochester (rŏch`ĕstər, –ĭstər). 1 City (1990 pop. 70,745), seat of Olmsted co., SE Minn.; inc. 1858. , N.Y. maker of off-line dimensional checking instruments for tubing, offers the new lenses for its Quest model SmartScope. Telecentric optics offer a higher quality image with less distortion distortion, in electronics, undesired change in an electric signal waveform as it passes from the input to the output of some system or device. In an audio system, distortion results in poor reproduction of recorded or transmitted sound. . They are common in shadow comparators and contour contour or contour line, line on a topographic map connecting points of equal elevation above or below mean sea level. It is thus a kind of isopleth, or line of equal quantity. projectors, but not in video imaging. |
