Abstract
Abstract For the adjustment and mounting of an optical component in an optical instrument, the optical component is held by an adjusting device not forming part of the instrument. After the adjusting process is completed, the component is attached to the instrument by a liquid or pasty substance which solidifies with slight change in volume. The optical component or its mount and the instrument are so developed that a form-locked, force-locked, or adherence-locked attachment is produced between them. The adjusting process can be made objective by a position-resolving receiver; the evaluation of the adjustment image and the carrying out of the adjustment movements can be effected by a computer which can also carry out the entire adjustment process completely automatically. After the firm attachment of the optical component to the instrument, the adjusting device is removed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
222 words
The method of adjusting the position of an optical unit relative to an optical instrument and mounting the optical unit on the optical instrument when the proper adjusted position has been determined, which comprises the steps of: (a) providing an optical instrument; (b) providing an optical unit to be adjusted relative to and then mounted on said instrument; (c) providing an adjusting device separate from said instrument and capable of supporting said optical unit and also capable of moving said optical unit in a plurality of directions in space and of rotating it about a plurality of axes of rotation in space; (d) attaching said device to said instrument and supporting said unit on said device; (e) operating said device to effect precise adjustment of said unit relative to said instrument while said unit is unconnected to said instrument except through said device; (f) firmly attaching said unit and said instrument to each other in the adjusted position of said unit by applying between adjacent portions of said unit and said instrument a flowable substance capable of hardening to form a firm connection; and (g) detaching said device from said unit and said instrument and removing said device, after said substance has hardened, leaving said unit mounted in adjusted position on said instrument and maintained in said position by said hardened substance.
Claim 2
Independent Claim
222 words
The method of adjusting the position of an optical unit relative to an optical instrument and mounting the optical unit on the optical instrument when the proper adjusted position has been determined, which comprises the steps of: (a) providing an optical instrument; (b) providing an optical unit to be adjusted relative to and then mounted on said instrument; (c) providing an adjusting device separate from said instrument and capable of supporting said optical unit and also capable of moving said optical unit in a plurality of directions in space and of rotating it about a plurality of axes of rotation in space; (d) attaching said device to said instrument and supporting said unit on said device; (e) operating said device to effect precise adjustment of said unit relative to said instrument while said unit is unconnected to said instrument except through said device; (f) firmly attaching said unit and said instrument to each other in the adjusted position of said unit by applying between adjacent portions of said unit and said instrument a flowable substance capable of hardening to form a firm connection; and (g) detaching said device from said unit and said instrument and removing said device, after said substance has hardened, leaving said unit mounted in adjusted position on said instrument and maintained in said position by said hardened substance.
Claim 3
Dependent Claim
28 words
The invention defined in claim 1, wherein said optical unit is attached to said instrument by a liquid or pasty substance which solidifies with slight change in volume.
Claim 4
Dependent Claim
19 words
The invention defined in claim 2, wherein said substance is a substance the soldification process of which is reversible.
Claim 5
Dependent Claim
13 words
The invention defined in claim 3, wherein said substance is a low-melting alloy.
Claim 6
Dependent Claim
68 words
The invention defined in claim 2, wherein said optical unit is developed in the manner that parts extend into at least one hollow space of the instrument, the hollow space being so developed that the optical unit is sufficiently movable for the intended adjustment, and that, after adjustment has been effected, the attaching substance is introduced into said hollow space and forms a form-locked attachment upon its solidification.
Claim 7
Dependent Claim
66 words
The invention defined in claim 2, wherein said optical unit and said instrument are developed in such a manner that a gap or gaps are produced between them, the gap or gaps being so developed that the optical unit is sufficiently movable for the intended adjustment, and that after adjustment the attaching substance is introduced into said gaps and forms a force-locked attachment upon its solidification.
Claim 8
Dependent Claim
75 words
The invention defined in claim 2, wherein said optical unit and said instrument are developed in such a manner that two approximately parallel surfaces are produced between them, the space between the surfaces being so developed that the optical unit is sufficiently movable for the adjustment, and that after the adjustment has been effected by the attaching substance is introduced into said space and upon its solidification forms an adherence-locked attachment by bonding or soldering.
Claim 9
Dependent Claim
