Abstract

1,248,362. Profile projection system. RANK ORGANISATION Ltd. Jan.28, 1970, No.4075/70. Addition to 1,173,962. Heading G2J. An optical measuring projector has an objective as defined in claim 1 of 1,173, 962, and includes provision for movement of the complete objective in toto relative to the body of the objective in predetermined relationship to the internal movements of the objective components so as to maintain constant the position of the image plane during variation of the object plane/image plane distance. The outer components A, A<SP>1</SP> of the lens are simultaneously and equally movable in opposite directions in association with converse simultaneous and equal movements in opposite directions of the inner components B, B<SP>1</SP> with respect to a diaphragm S. The laws of movement of the inner and outer components are both substantially linear with respect to the change in object plane/ image plane distance. The overall movement of the objective and the movements of the inner and outer components are governed by a single control element through a screw thread and simple linear levers. Optical data for the objective is also given.
