Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
A method of aligning the axis (25) of a longitudinally-extending source (15) of high-intensity radiation with the axis ( 0) of optical apparatus (10) incorporating the source, including the steps of: a) supporting the source in a position in which the two axes intersect at a known point (P), and b) pivoting the source about the said point until the axes are coaxial.
Claim 2
Independent Claim
63 words
A method of aligning the axis (25) of a longitudinally-extending source (15) of high-intensity radiation with the axis ( 0) of optical apparatus (10) incorporating the source, including the steps of: a) supporting the source in a position in which the two axes intersect at a known point (P), and b) pivoting the source about the said point until the axes are coaxial.
Claim 3
Dependent Claim
17 words
A method as claimed in claim 1, including the further step of securing the source in position.
Claim 4
Dependent Claim
60 words
Optical apparatus (10) including a longitudinally-extending source (15) of high-intensity radiation; means (63, 66) for supporting the source in a position in which the axis (25) of the source intersects the axis ( 0) of the optical appartus at a known point (P) and means (78; 81) for pivoting the source about the said point until the axes are coaxial.
Claim 5
Dependent Claim
60 words
Optical apparatus (10) including a longitudinally-extending source (15) of high-intensity radiation; means (63, 66) for supporting the source in a position in which the axis (25) of the source intersects the axis ( 0) of the optical appartus at a known point (P) and means (78; 81) for pivoting the source about the said point until the axes are coaxial.
Claim 6
Dependent Claim
29 words
The appartus according to claim 3, including means for securing the source in position after coincidence between the axis of said beam and said apparatus optical axis is obtained.
Claim 7
Dependent Claim
35 words
The apparatus according to claim 3 or 4, in which said supporting means (58) is provided at the discharge end of said source, and in which the pivoting means (77) engage the other end thereof.
Claim 8
Independent Claim
54 words
The apparatus according to any of claims 3-5, in which the radiation source comprises a laser plasma tube (22), and a housing (57) for said tube, said tube being disposed in said housing so that intersection of the two axes is achieved by fixing the position of the housing relative to the optical axis.
Claim 9
Independent Claim
29 words
The apparatus according to any of claims 4-6, in which said supporting means forms a joint adapted to pivot about a point, which is coincident with the said point.
Claim 10
Dependent Claim
17 words
Apparatus as claimed in any of claims 3-7, in which the optical apparatus is a raster scanner.
Claim 11
Dependent Claim
48 words
Apparatus as claimed in claims 7 and 8, in which the pivotal joint includes a frustoconical surface (63) movable with the housing (15) of the radiation source, and a part-spherical member (66) mounted on the chassis of the optical apparatus and in line contact with the frustoconical surface.
