From 1951 USAF resolution test charts to almost any custom test targets imaginable, Opto-Line can produce any pattern you need with pinpoint precision and accuracy.
It is still widely accepted to test the resolution of optical imaging systems such as microscopes, cameras and image scanners. For the 1951 USAF, the common format consists of six “groups” in three layers of patterns. The largest groups, forming the first layer, are located on the outer sides. The smaller layers repeat the same pattern but are progressively smaller toward the center. Each group consists of six elements, numbered from 1 to 6. Within the same layer, the odd-numbered groups appear contiguously from 1 through 6 from the upper right corner. The first element of the even-numbered groups is at the lower right of the layer, with the remaining 2 through 6, at the left. However, Opto-Line can delineate to the 8th group, 6th element (456 line pairs/mm).
Opto-Line is dedicated to the highest quality custom optical patterns and coatings.
Since 1967, Opto-Line International has built a reputation for excellence, providing companies in the medical, optometry, aerospace, industrial, science and defense sectors with the very best custom precision optical patterns and thin film coatings available.
