1,040,678. Optical range finders. CARL ZEISS-STIFTUNG, [trading As CARL ZEISS]. June 24, 1965 [June 30, 1964], No. 26738/65. Heading G2J. An optical range finder comprises two telescope systems each with an objective lens F 1 , F 1 <SP>1</SP> with a measuring mark M, M<SP>1</SP> and a small illuminating prism P, p<SP>1</SP>, a prism system 3, 3<SP>1</SP> mounted on a rotatable micrometer knob 10, a dispersing lens F 2 , F 2 <SP>1</SP> cemented to prisms 3, 3<SP>1</SP> respectively, an objective lens F 3 , F 3 <SP>1</SP>, a prism 5, 7 a reversing lens F 4 , F 4 <SP>1</SP> and an eyepiece 0, 0<SP>1</SP>. The images first of the marks M, M<SP>1</SP> and then of the sighted object are combined to form a stereoscopic picture by rotating the prism combination 3, 3<SP>1</SP> about axis 3<SP>11</SP>. By inserting a mirror 4 in the first system and a semi-transparent mirror 6 in the second system, the two images are seen through eyepiece 0<SP>1</SP>, the images being brought into coincidence by rotating the prism combination 3, 3<SP>1</SP>.
