Appl. No.:

09/846386

Eric C. Hansell - New Milford CT 06776
Jose V. Herrera - Stratford CT 06615

International Classification:

G03B 2752

US Classification:

355 30

Abstract:

A method and apparatus for providing a purged optical path between an optical source surface and an optical target surface and for permitting relative movement between the optical source surface and the optical target surface is described. The apparatus includes a body, a central cavity, at least one gas supply bore, and at least one gas removal bore. The body defines first and second opposing surfaces. The first opposing surface is configured for positioning closely adjacent to the optical target surface. The second opposing surface is configured to mate with the optical source surface. The central cavity is formed in the body for passing light through the body, the central cavity being open at the first and second opposing surfaces. The at least one gas supply bore is formed in the body for suppling a flow of a purge gas to the central cavity. The at least one gas removal bore is formed in the body at the first opposing surface to remove gas from a gap formed between the first opposing surface and the optical target surface.

Assignee:

The Perkin-Elmer Corporation - Norwalk CT

International Classification:

G02B 702

US Classification:

350252

Abstract:

A lens mount including a lens cell wherein a lens is mounted through flexures. The lens seat in the lens cell has a radius of curvature match-mated to the lens surface which rests upon it. The rotational symmetry axis of the lens seat is coincident with the axis of rotation of the lens cell. The optical axis of the second lens surface is coincident with the axis of rotation of the lens cell.

Anees Ahmad - Bethel CT
Richard Huse - Norwalk CT

Assignee:

The Perkin-Elmer Corporation - Norwalk CT

International Classification:

G02B 718

US Classification:

350609

Abstract:

A mirror mounting apparatus which includes three tangent bars through which a mirror is mounted to a housing. One end of each of the tangent bars is mounted to the housing through a first spherical bearing while the second end of the tangent bar is mounted to the mirror through a second spherical bearing. The first spherical bearing has an axis perpendicular to the plane of the mirror. The second spherical bearing is oriented to have an axis perpendicular to both the axis of the first spherical bearing and to a line tangent to the point of attachment on the outer circumference of the mirror of the tangent bar.

Inventors:

Anees Ahmad - Bethel CT
Richard L. Huse - Norwalk CT

Assignee:

The Perkin-Elmer Corporation - Norwalk CT

International Classification:

G02B 718

US Classification:

350633

Abstract:

A mirror mount wherein the mirror is mounted to the housing through tangent bars. The tangent bars have flexure cut-outs at each end thereof to allow the mirror to move relative to the housing. The housing is mounted through blade flexures to a support structure so as to allow the mirror to be translated along its optical axis.
