Resolution test targets provide an established method for testing the resolution of optical imaging systems. The 1951 USAF resolution test target remains widely accepted for testing systems such as microscopes, cameras, and image scanners.

At Opto-Line International, we produce both well-known standard test patterns as well as custom test patterns to meet a wide range of precision optical testing requirements. We’d love to hear from you to learn more about your test pattern needs.
