Abstract
Abstract An apparatus for irradiating a specimen with a laser beam in a hot cell comprising a laser generator located outside the cell and an observation channel for remote adjustment of the specimen. The laser beam and the observation channel are in a common duct with their axes parallel to each other. A movable mirror system in the observation channel near the specimen is used to bring the two axes into coincidence when an observation is to be made.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
Apparatus for observing and irradiating a specimen with a laser beam in a hot cell comprising a shielding wall, a nonrectilinear duct passing therethrough, emitter means outside said wall for generating a laser beam, an afocal optical system for said laser beam mounted in said duct, a second optical system mounted with its axis substantially parallel to the axis of said afocal system with an eyepiece outside said wall, a movable mirror system inside said wall near said specimen which mirror in one position reflects the axis of said second optical system into the axis of the afocal system so that the image points of both systems coincide.
Claim 2
Dependent Claim
108 words
Apparatus for observing and irradiating a specimen with a laser beam in a hot cell comprising a shielding wall, a nonrectilinear duct passing therethrough, emitter means outside said wall for generating a laser beam, an afocal optical system for said laser beam mounted in said duct, a second optical system mounted with its axis substantially parallel to the axis of said afocal system with an eyepiece outside said wall, a movable mirror system inside said wall near said specimen which mirror in one position reflects the axis of said second optical system into the axis of the afocal system so that the image points of both systems coincide.
Claim 3
Dependent Claim
55 words
Apparatus as claimed in claim 1, in which the laser emitter is in alignment with the aperture provided in the wall for the duct, and the eyepiece is situated out of alignment with the wall aperture, by way of at least one further diversion of the axis of the second optical system associated with it.
Claim 4
Dependent Claim
42 words
Apparatus as claimed in claim 2, in which an observation instrument is movable into the path of the laser beam between the laser emitter and the wall, and the coincidence of the two systems can be verified by means of this instrument.
