Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A telescope comprising in a housing an ocular, an objective an image reversing system, arranged between said ocular and said objective, said ocular and said objective having in common an image plane and a folded optical axis, said image reversing system comprising two right angle prisms and being in optical alignment with said ocular and said objective, at least one of said prisms being adjustably mounted on said housing, a prism mount for receiving said adjustable prism, a slide, being rigidly connected to said prism mount, a guide being arranged at right angles relative to the part of the optical axis which is in the vicinity of said ocular, said slide being displaceable in said guide, a seating body being fast with said guide, a seating, said seating body being tiltably seated in said seating about an axis of rotation being in parallel with said guide, a trunnion being secured to said seating at right angles to said axis of rotation, a sliding bearing being connected to said housing, said trunnion being rotatably and displaceably arranged in said sliding bearing.
Claim 2
Dependent Claim
