Resolution Charts or Test Charts to test optical characteristics such as resolution contrast, distortion, modulation transfer function (MTF) of lenses, cameras and optical systems. There is a wide variety of these products on our optics website, click here
Most resolution charts are made with a chrome on glass image, but are also available on Nextrema white glass where high contrast is required - click here for link.
For testing of thermal imaging systems we have the unique R74 USAF foil test chart
Manufactured as chrome on glass or in electroformed metal foil, Modulation Transfer Function patterns are blocks of multiple slits used in MTF testing. Size and layout of the slit blocks and their angles can be defined to suit the application.
