Test Targets

Test Targets are used to measure the accuracy or performance of an imaging system to ensure effective functioning. Test Targets are selections of slides or windows that are integrated into imaging systems to measure a number of imaging characteristics including resolution, distortion, or color/grayscale. Test Targets often feature an array of lines, dots, or other patterns which an imaging system focuses on in order to determine its level of precision. Test Targets allow imaging systems to maintain a high level of accuracy over time or multiple applications.

Edmund Optics offers a wide range of Test Targets suited for many imaging systems. Test Targets are designed to easily integrate into an imaging system for quick, easy setup. Test Targets may be used repeatedly with any number of different systems, allowing a small number of targets to service large numbers of imaging systems. Test Targets are available in glass, chrome, or photographic paper for multiple compatibility options for ease of use.
