High mangification lens distortion
 - Wikipedia)
Distortion is specified as a percentage of the field height. Typically, ±2 to 3% distortion is unnoticed in a vision system if measurement algorithms are not used. In simple lenses, there are two main types of distortion: negative, barrel distortion, where points in the FOV appear too close to the center; and … See more Figure 3shows negative, or barrel, distortion in a 35mm lens system. In this example, all the wavelengths analyzed have almost identical distortion, thus wavelength-related issues are not present. In Figure 4, an … See more In lens datasheets, distortion is usually specified in one of two ways: radial, geometric distortion or RIAA TV distortion. Geometric distortion is the distance between where points appear in the distorted image and … See more In addition to the previous distortion types mentioned, which are inherent to the optical design of a lens, improper system alignment can result … See more WebSep 10, 2024 · Common Optical Defects in Lens Systems (Aberrations) Microscopes and other optical instruments are commonly plagued by lens errors that distort the image by a variety of mechanisms associated with …
