Resolution Test Targets

Resolution Test Targets are used to measure the accuracy or performance of an imaging system for applications such as microscopy or imaging. Resolution Test Targets are inserted into an imaging system to provide measurement capabilities. Resolution Test Targets use a variety of patterns including Ronchi or star to measure a system’s resolution. High precision models are also available for demanding or precise measurement requirements.

Edmund Optics offers a wide range of Resolution Test Targets suited for many imaging measurement needs. Resolution Test Targets provide the user the ability to easily measure the accuracy of an imaging system, extending a system’s lifecycle by maintaining its effectiveness after continued use or time. Star targets feature a circle of converging lines that measure resolution by determining how far an imaging system can distinguish individual lines. Ronchi targets similarly use a series of fine lines to measure an imaging system’s performance. Many Resolution Test Targets are available in both glass slide as well as photographic paper versions.
