Filed:

Dec 18, 2002

Appl. No.:

10/325648

Inventors:

Alex Harwit - San Mateo CA
Paul Robb - Sunnyvale CA
Janusz Liberkowski - San Jose CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G02B 2710

US Classification:

359619, 359526

Abstract:

The present invention is directed towards a focus-position compensator for reducing focus variations on a microlens array. The focus-position compensator comprises a plurality of tiles that are affixed to a structure disposed between the lenslets of the microlens array and the target of the collimated light from the lenslets. Each tile refractive index and tile thickness is chosen to obtain a tile focus-position correction that will apply to a region of the microlens array.

7/379454

Inventors:

Paul N. Robb - Sunnyvale CA

Assignee:

Lockheed Missiles & Space Company, Inc. - Sunnyvale CA

International Classification:

G02B 312
G02B 960

US Classification:

350418

Abstract:

An apochromatic lens system consisting of four identical glass lens elements and a liquid lens element is disclosed, which has a change in focus of less than one-quarter wavelength over the entire visible spectrum. The glass lens elements and the liquid lens element are made from relatively inexpensive commercially available optical materials.

International Classification:

G02B 106
G02B 312

US Classification:

359665

Abstract:

Design forms are disclosed for 5X and 10X laser beam expanders whose lens elements consist only of plastic and liquid optical materials, which provide diffraction-limited performance without refocussing over a wavelength range from 0. 4 micron to 0. 8 micron.

US Classification:

359355

Abstract:

Lens systems (8, 18, 28, 38, 48, 58) with first and second rigid lens elements and a liquid lens element therebetween are provided. The first and second rigid lens elements (10, 11; 20, 21; 30, 31; 40, 41; 50, 51; 60, 61) and the liquid lens elements (16, 26, 36, 46, 56, 66) co-act with each other to cause the lens system to have substantially diffraction limited performance over a continuous ultraviolet wavelength band, wherein the first and second rigid lens elements and the liquid lens element are configured and positioned with respect to each other according to a selection of particular designs and design forms.

Inventors:

Paul N. Robb - Sunnyvale CA

Assignee:

Lockheed Missiles & Space Company, Inc. - Sunnyvale CA

International Classification:

G02B 1306
G02B 912

US Classification:

350463

Abstract:

Design forms for wide-field mapping lenses are disclosed wherein limitations on resolving power attributable to monochromatic aberrations have been minimized, wherein chromatic aberration has been minimized over a broad wavelength band and has been reduced to zero for paraxial marginal rays at three discrete wavelengths, and wherein chromatic variations of the monochromatic aberrations (particularly chromatic variation of coma) have been substantially eliminated. Each of the lenses disclosed has an aperture diameter in the range from 10 to 15 inches, a focal length in the range from 200 to 300 inches, and a circular field of view in the range from 40. degree. to 60. degree. Further, each lens is diffraction limited in a spectral range from 0. 50 to 0. 80 micron over the entire field of view. The focal surface for each lens disclosed is curved, so that illumination fall-off from the center to the edge of the focal surface varies by a factor of only about cos. sup. 1. 5. theta. , where. theta.
