Dot Array 50mm x 50mm, .125mm Dots on .25mm Centers, Mylar These precision Mylar Distortion Targets allow for the testing and qualification of machine vision systems. The pattern is formed in film emulsion on a .007” Mylar substrate. The pattern is positive (black dots on a diffuse white background). Targets are available in four different patterns and three substrate sizes to match the requirements of your application. These film targets have a feature-to-feature accuracy of .005mm. All targets are NIST traceable and individually serialized for compliance to MIL-STD-45662A. For higher accuracy, please see the Chrome-on-Glass version of this target. Dot diameter: .125mm Dot spacing: .25mm Overall Accuracy: ±0.025mm Substrate type: film on white mylar Substrate size: 3” x 3” Please see the drawing in the Specifications tab for complete specifications.
