Optics distortion
WebGeometrical Distortion. Distortion is an aberration commonly seen in stereoscopic microscopes, and is manifested by changes in the shape of an image rather than the sharpness or color spectrum. The two most … WebDistortion is produced mainly by the oculars (between 5 and 10 percent of the radial distance) in optical microscopy, although some distortion is also found in lower quality objectives. Microscopes can be monitored for …
