Abstract
Abstract An instrument for viewing and measuring electromagnetic radiation, wherein an image-receiving web of an image-receiving screen is formed by successively arranged layers comprising: a heat insulation backing layer, a metal layer and a luminophore layer, the image-receiving web being secured on a holder, the image-receiving screen and an excitation source are enclosed within a housing provided with windows for the passage of the electromagnetic radiation; the screen with its holder is preferably enclosed within a protective case also provided with windows for the passage of the electromagnetic radiation being measured.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
An apparatus for viewing and measuring electromagnetic radiation, comprising: a housing, and image-receiving screen mounted in said housing, said screen including an image-receiving web including at least three successive layers, the first of said layers being a heat insulation backing, another one of said layers being a metal layer adapted to absorb said radiation and having a thickness of 5 to 200A., and the third of said layers being a layer of luminophore the luminescence of which is responsive to said radiation; holder means having said imagereceiving web of said screen secured thereto; at least one source of excitation of said luminophore, also mounted in said housing adjacent to said screen.
Claim 2
Independent Claim
111 words
An apparatus for viewing and measuring electromagnetic radiation, comprising: a housing, and image-receiving screen mounted in said housing, said screen including an image-receiving web including at least three successive layers, the first of said layers being a heat insulation backing, another one of said layers being a metal layer adapted to absorb said radiation and having a thickness of 5 to 200A., and the third of said layers being a layer of luminophore the luminescence of which is responsive to said radiation; holder means having said imagereceiving web of said screen secured thereto; at least one source of excitation of said luminophore, also mounted in said housing adjacent to said screen.
Claim 3
Dependent Claim
12 words
An apparatus according to claim 1, wherein said housing is hermetically sealed.
Claim 4
Dependent Claim
48 words
An apparatus according to claim 1, wherein said image-receiving screen is built up from a plurality of said image-receiving webs having individual holder means, each said web being secured on its individual holder means, all said holders of said plurality of webs being mounted in a single frame.
Claim 5
Dependent Claim
59 words
An apparatus according to claim 1, wherein said holder means includes two concentric rings, whose adjoining surfaces are tapered at an identical angle of several degrees and one of which is received within the other, whereby an uniform stretching of said image-receiving web of said screen is made possible, said web being secured intermediate of said pair of rings.
Claim 6
Dependent Claim
19 words
An apparatus according to claim 1, further comprising a casing having windows, said screen being disposed within said casing.
Claim 7
Dependent Claim
38 words
An instrument according to claim 5, wherein said casing hermetically sealed and incorporates an evacuation control valve, said casing being filled through said valve with various gases under pressures ranging from 10 3 mm Hg to 10 atm.
Claim 8
Dependent Claim
32 words
An apparatus according to the claim 5, wherein at least one of said windows is set at an angle with respect to the path of said radiation, e.g., at a Brewster angle.
Claim 9
Dependent Claim
30 words
An apparatus according to claim 5, wherein said casing incorporates a heater means and a temperature control device adapted to maintain the temperature of said screen at a desired level.
Claim 10
Dependent Claim
18 words
An apparatus according to claim 1, wherein said source of excitation includes a lamp of a toroidal shape.
