Abstract

Features of designing objectives telecentric in object space are discussed. The optical circuits of three telecentric objectives developed for dimensional control systems using the shadow projection method are presented. A quality control method for the manufacture of such objectives which have small distortion (less than 0.02 %) and small non-telecentricity (less than 0.01º) is described. Comparison of experimentally obtained optical characteristics of two objectives manufactured by us and one objective manufactured by the Thorlabs company (U.S.) is carried out.
