Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
67 words
A laser beam manipulator device comprising: an enclosure; an opening in said enclosure defining therein a working area in which may be received an object to be treated; means for receiving the laser beam within said enclosure and for conducting it to said opening; and means for intercepting the laser beam adjacent the opening, whereby the beam is prevented from emerging through the opening in the enclosure.
Claim 2
Dependent Claim
67 words
A laser beam manipulator device comprising: an enclosure; an opening in said enclosure defining therein a working area in which may be received an object to be treated; means for receiving the laser beam within said enclosure and for conducting it to said opening; and means for intercepting the laser beam adjacent the opening, whereby the beam is prevented from emerging through the opening in the enclosure.
Claim 3
Dependent Claim
89 words
A device according to claim 1 wherein: said object-receiving opening is formed at one end of the manipulator; said laser beam receiving and conducting means directs the laser beam at a reflecting means at one side of said opening oriented for reflecting the laser beam across said opening; and said means for intercepting the laser beam comprises said reflecting means and means at the opposite side of said opening that intercepts the laser beam after it has been reflected by said reflector and has passed through said working area.
Claim 4
Dependent Claim
92 words
A device according to claim 1 wherein: said object-receiving opening is formed at one end of the manipulator and coaxial with the longitudinal axis thereof; the means for intercepting the laser beam comprises an apertured reflecting means around the object-receiving opening of the manipulator; the laser beam receiving and conducting means comprises means for directing the laser beam at the apertured reflecting means and not the opening around which it is located; and said reflecting means is oriented to reflect the incident laser beam in a direction other than through said opening.
Claim 5
Dependent Claim
23 words
A device according to claim 3 wherein said receiving and conducting means include means for forming a laser beam into two spaced-apart sections.
Claim 6
Dependent Claim
41 words
A device according to claim 4 wherein said means for forming a laser beam into two spaced-apart sections comprises a pair of spaced-apart mirrors disposed in the manipulator to receive the laser beam and to reflect it toward the object-receiving opening.
Claim 7
Dependent Claim
34 words
A device according to claim 5 wherein said manipulator further comprises an illuminating device and an eyepiece oriented for illuminating and observing said working area through the spaced-apart region between said pair of mirrors.
Claim 8
Dependent Claim
15 words
A device according to claim 3 wherein said laser beam has an annular cross section.
Claim 9
Dependent Claim
20 words
A device according to claim 3 wherein said apertured reflecting means comprises an annular concave mirror surrounding the object-receiving opening.
Claim 10
Dependent Claim
47 words
A device according to claim 3 wherein: the reflecting means are oriented to reflect incident radiation across the object-receiving opening; and the laser beam receiving and conducting means further comprises means for bringing said laser beam to focus within said opening after reflection from said reflecting means.
Claim 11
Dependent Claim
53 words
A device according to claim 1 wherein said manipulator includes a shaft along which the laser beam is conducted, an object-receiving opening in a sidewall of said shaft, and an end wall extending across said shaft and intercepting the laser beam after it has passed through the working area defined by said opening.
