46052828, Aug 12, 1986

Filed:

Dec 22, 1983

Appl. No.:

6/564562

Inventors:

Paul L. Fox - Whittier CA

Assignee:

Pyramid Optical, Inc. - Irvine CA

International Classification:

G02B 302

US Classification:

350167

Abstract:

An improved line lens for producing output radiation in the form of a narrow sheet from a collimated input beam despite the use of a lens material having an index of refraction of less than 1. 6. A novel design method permits redistribution of output energy as a function of angle along the surface of the lens to achieve the specified output pattern and defines the polynomials of the contoured surface curves of such a lens. In one embodiment of such a lens, which is designed by the inventive method, the input shape is contoured by circular segments and the exit surface is contoured according to the design-method-produced polynomials.

Abstract:

A method of constructing a lens of the type receiving a collimated beam of input radiation for transmitting a narrow sheet of output radiation of substantially uniform intensity over an angular range of approximately + and -45 degrees relative to the input radiation beam. The method includes steps relating to defining the lens surface geometry and to implementing that geometry on a transmissive material having an index of refraction no greater than 1. 6. The implementation of the method employs grinding and polishing steps which may be carried out by a disclosed lapping machine.
