Abstract
Abstract A periscope-like sighting device is proposed which comprises an optical system comprising a plurality of elements arranged within a housing for localizing and tracking a target. In order to obtain as great as possible a field of observation, the optical system comprising a first deflection prism, an objective lens or lens system, a first beam splitter, a second beam splitter and a second deflection prism is arranged in the housing sloping backward in the direction of incident radiation and in relation to a vertical rear housing wall. A main mirror is associated with the first beam splitter and is journaled in a mirror head arranged sloping backward in the housing to be pivotable about a first axis and rotatable about a second axis. In order to achieve a range-finding of the target, a laser range finder can be arranged on the housing of the sighting device and is preferably subdivided into a laser transmitter portion and a laser receiver portion and the principal components of the laser receiver portion are arranged within the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
A periscope-like sighting device comprising: a housing; a multiple-element optical system arranged in said housing and intended for the localization and tracking of a target, said optical system comprising: a first deflecting prism; objective lens means; a first beam splitter; a second beam splitter; a second deflecting prism; a main mirror operatively associated with said first deflecting prism; said main mirror and the optical system being arranged in the housing to slope backward from bottom to top in relation to a substantially vertical rear wall of the housing in a direction of incident radiation; the main mirror being mounted in a mirror head arranged sloping backward in the housing to perform a pivoting motion about a first axis; and the main mirror being mounted to perform a rotating motion about a second axis conjointly with said mirror head.
Claim 2
Dependent Claim
138 words
A periscope-like sighting device comprising: a housing; a multiple-element optical system arranged in said housing and intended for the localization and tracking of a target, said optical system comprising: a first deflecting prism; objective lens means; a first beam splitter; a second beam splitter; a second deflecting prism; a main mirror operatively associated with said first deflecting prism; said main mirror and the optical system being arranged in the housing to slope backward from bottom to top in relation to a substantially vertical rear wall of the housing in a direction of incident radiation; the main mirror being mounted in a mirror head arranged sloping backward in the housing to perform a pivoting motion about a first axis; and the main mirror being mounted to perform a rotating motion about a second axis conjointly with said mirror head.
Claim 3
Dependent Claim
15 words
The sighting device as defined in claim 1, wherein: said incident radiation is visible radiation.
Claim 4
Dependent Claim
15 words
The sighting device as defined in claim 1, wherein: said incident radiation is invisible radiation.
Claim 5
Dependent Claim
27 words
The sighting device as defined in claim 1, wherein: said optical system is arranged upon a carrier member to be installed as a sub-assembly in the housing.
Claim 6
Dependent Claim
41 words
The sighting device as defined in claim 1, wherein: a retaining member is arranged on said vertical rear wall of the housing at an angle of essentially 25° relative to the vertical rear wall of the housing for accommodating an ocular.
Claim 7
Dependent Claim
37 words
The sighting device as defined in claim 5, further including: a carrier member for supporting said optical system; and said retaining member for said ocular is arranged upon said carrier member and forms a constructional unit therewith.
Claim 8
Dependent Claim
58 words
The sighting device as defined in claim 1, wherein: said mirror head comprises: a first code disk; a second code disk; integral drive mechanisms for said pivoting motion and said rotating motion; and the mirror head being constructed as a sub-assembly and arranged in a sloping orientation in the housing and fixed to a floor of the housing.
Claim 9
Dependent Claim
50 words
The sighting device as defined in claim 1, wherein: said mirror head is essentially U-shaped and has two essentially vertical side members; said mirror head comprising a carrier plate for said main mirror; and said carrier plate being journaled in said two side members to pivot about said first axis.
Claim 10
Dependent Claim
55 words
The sighting device as defined in claim 1, further including: a carrier member for supporting said optical system; a laser range finder fixed to said vertical rear wall of the housing; and said laser range finder possessing a receiver portion integrated into said optical system and arranged in the housing conjointly with said carrier member.
Claim 11
Dependent Claim
44 words
