Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A monolithic mirror objective comprising a lens having a first mirror, primary mirror, arranged in connection with the output surface of the lens and a second mirror, secondary mirror, arranged in connection with the input surface of the lens, the mirrors in cooperation with the lens being arranged to form an N-shaped radiation path through the mirror objective, characterized in that the first mirror is arranged to cover the central part of the output surface, while the second mirror is arranged to cover a part of the input surface which is displaced aside relative to the center of the input surface, so that the first mirror and the second mirror together with the lens and possible further lenses can follow excentrically running, N-shaped path through the objective, the object and the image situated on each side of the geometrical axis of the mirror objective.
Claim 2
Dependent Claim
144 words
A monolithic mirror objective comprising a lens having a first mirror, primary mirror, arranged in connection with the output surface of the lens and a second mirror, secondary mirror, arranged in connection with the input surface of the lens, the mirrors in cooperation with the lens being arranged to form an N-shaped radiation path through the mirror objective, characterized in that the first mirror is arranged to cover the central part of the output surface, while the second mirror is arranged to cover a part of the input surface which is displaced aside relative to the center of the input surface, so that the first mirror and the second mirror together with the lens and possible further lenses can follow excentrically running, N-shaped path through the objective, the object and the image situated on each side of the geometrical axis of the mirror objective.
Claim 3
Dependent Claim
51 words
A mirror objective as claimed in Claim 1, characterized in that an input slot is disposed in front of the input surface and an output slot is disposed after the output surface in order to together with the shaping of the mirrors delimit the radiation beam passing through the mirror objective.
Claim 4
Dependent Claim
31 words
A mirror objective as claimed in Claim 1, characterized in that a further lens is disposed adjacent to said lens, one of the reflecting surfaces being enclosed between the two lenses.
Claim 5
Dependent Claim
28 words
A mirror objective as claimed in any one of the preceding Claims, characterized in that a collimator lens is disposed near the object plane of the mirror objective.
Claim 6
Dependent Claim
61 words
An optical arrangement comprising two mirror objectives as claimed in any one of the preceding Claims, characterized in that the two mirror objectives are arranged with parallel geometrical axes and adjacent to each other, and in that one of the mirror objectives is used for illuminating an object while the other mirror objective is used for imaging the object in question.
