1 August 1984 Straightness Measurement System For Slits
Author Affiliations +
An optical system was developed to measure the straightness of a slit to better than 0.04 Am peak-to-peak. The slit (part of a reticle pattern) was 19 Am wide and 25 mm long, lying across the center of one face of a convex spherical lens. The system demonstrated a 0.02 Am peak-to-peak measure-ment repeatability, with a capability of achieving higher accuracy.
