Fabrication Of Unit Lenses For Compound Refractive Lenses

View page
US Patent:
6674583, Jan 6, 2004
Filed:
Jun 25, 2002
Appl. No.:
10/179089
Inventors:
Hector R. Beguiristain - Oakland CA
Jay T. Cremer - Palo Alto CA
Melvin A. Piestrup - Woodside CA
Assignee:
Adelphi Technology, Inc. - Palo Alto CA
International Classification:
G02B 900
US Classification:
359754, 359646, 359796, 359717
Abstract:
A compound refractive lens for focusing, collecting, collimating and imaging with x-rays comprising N unit lenses numbered i=1 through N unit lenses substantially aligned along an axis such that i-th lens having a displacement t orthogonal to said axis, with said axis located such that the sum of the lens displacements t equals zero, and wherein each of said unit lenses comprises a lens material of lithium, carbon, or polyimide. A method for molding and housing the unit lenses is provided such that the unit lens have high surface and optical quality, and do not chemically deteriorate due to absorption of water or oxidation.

US Patent:
6765197, Jul 20, 2004
Filed:
Sep 27, 2001
Appl. No.:
09/965501
Inventors:
Melvin A. Piestrup - Woodside CA
Richard H. Pantell - Portola Valley CA
Hector R. Beguiristain - Oakland CA
Assignee:
Adelphi Technology Inc. - Redwood City CA
International Classification:
R01S 100
US Classification:
250251, 2505051
Abstract:
A compound refractive lens for neutrons is provided having a plurality of individual unit Fresnel lenses comprising a total of N in number. The unit lenses are aligned substantially along an axis, the i-th lens having a displacement t orthogonal to the axis, with the axis located such that Each of the unit lenses comprises a lens material having a refractive index decrement 1 at a wavelength 200 Angstroms. In a preferred mode, the lens above is configured such that the displacements t are distributed and have a standard deviation of the displacements t about the axis, and wherein each of the unit lens has a smallest Fresnel zone width of s -s , where s and s are the zone radii of the n and n-1 zones and the standard deviation is [s -s ]/4.

US Patent:
62691457, Jul 31, 2001
Filed:
May 7, 1999
Appl. No.:
9/307289
Inventors:
Melvin A. Piestrup - Woodside CA
Richard H. Pantell - Portola Valley CA
Jay T. Cremer - Palo Alto CA
Hector R. Beguiristain - Oakland CA
Assignee:
Adelphi Technology, Inc. - Palo Alto CA
International Classification:
G21K 106
US Classification:
378 81
Abstract:
In accordance with the present invention, a compound refractive lens for focusing, collecting and collimating x-rays comprising N individual unit lenses numbered i=1 through N, with each unit lens substantially aligned along an axis such that the i-th lens has a displacement t. sub. i orthogonal to said axis, with said axis located such that the sum of the displacements t. sub. i equals zero, and wherein each of said unit lenses comprises a lens material having a refractive index decrement less than 1 at a wavelength less than 100 Angstroms.
