Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
An optical system for a camera, comprising: a. a first objective lens for forming a real image on a plane of the space under observation; b. a second objective lens having a principle focal point, F, positioned adjacent to a portion of said real image plane of the space under observation; plate; c. an eyepiece aligned with output means from said second objective lens, for projecting a real image of said portion on a photosensitive plate: and d. mechanical means for tilting said second objective lens with respect to the optical axis of said eyepiece and axially moving said second objective lens along the optical axis of said eyepiece for focusing the said second objective on the said real image of the space under observation.
Claim 2
Dependent Claim
125 words
An optical system for a camera, comprising: a. a first objective lens for forming a real image on a plane of the space under observation; b. a second objective lens having a principle focal point, F, positioned adjacent to a portion of said real image plane of the space under observation; plate; c. an eyepiece aligned with output means from said second objective lens, for projecting a real image of said portion on a photosensitive plate: and d. mechanical means for tilting said second objective lens with respect to the optical axis of said eyepiece and axially moving said second objective lens along the optical axis of said eyepiece for focusing the said second objective on the said real image of the space under observation.
Claim 3
Dependent Claim
49 words
An optical system as recited in claim 1, wherein the optical axis of the eyepiece and of the second objective are coaxial and wherein the mechanical tiltable means enable the optical axis of the second objective to pivot in a plane passing through the optical axis of the eyepiece.
Claim 4
Dependent Claim
27 words
An optical system as recited in claim 1, wherein the first objective has a variable focal distance, and including mechanical means to adjust the said focal distance.
Claim 5
Dependent Claim
30 words
An optical system as recited in claim 1, wherein the second objective is pivotable about the optical axis of the eyepiece and including mechanical means to pivot said second objective.
Claim 6
Dependent Claim
18 words
An optical system as recited in claim 1, wherein the eyepiece consists of a variable focal distance lens.
Claim 7
Dependent Claim
49 words
An optical system as recited in claim 1, mounted on a television camera wherein the first objective and the eyepiece have variable focal distance and devices to automatically adjust the said focal distances and an arrangement to automatically pivot the second objective about the optical axis of the eyepiece.
Claim 8
Dependent Claim
24 words
An optical system as recited in claim 1, wherein a graticule is located in the plane of the image formed by the first objective.
Claim 9
Dependent Claim
55 words
An optical system as recited in claim 1 wherein the mechanical means tilts the second objective lens and simultaneously axially moves the second objective lens whereby for every small indication angle of the second objective lens the focal point F is maintained closely positioned adjacent to said real image plane of the space under observation.
