Title:
OPTICAL ELEMENT HAVING AN INTEGRAL SURFACE DIFFUSER
Document Type and Number:
WIPO Patent Application WO2000011498
Kind Code:
A9
Abstract:
A monolithic element (20) has a substrate body (22) and at least one macro-optical characteristic integral (24) in a first portion of the optical element. A plurality of surface micro-structures (26) are integral in a portion of the optical element. The micro-structures (26) are designed to homogenize light passing through the optical element to produce a predetermined pattern of smoothly varying, non-discontinuous light exiting the optical element. The light exiting the optical element is therefore altered according to both the macro-optical characteristic of the optical element as well as the homogenizing characteristics of the micro-structures (26).
