Embodiment Construction

[0023] Several methods for optically or mechanically forming microlithographic surface structures or microstructures on substrates are set forth in the above-mentioned patents and pending patent applications belonging to the assignee of the present invention. The properties of the microstructure are random and produce a light output that is emitted through the substrate or reflected from the substrate with a smooth, uniform and continuous intensity distribution and controlled adjustment of direction and predetermined distribution shape or envelope. The above issued patents are directed to the application of various methods to form microstructures on photosensitive materials and to replicate the structures as negative-master structures. The negative-master structure is used to further replicate the microstructure onto the material sheet. The sheet of material can be coated or coated on the objective to achieve light uniformity, orientation and shaping properties. The above-me...

Abstract

A device (10) has a carrier (11) and an optical element (12) supported by the carrier. The optical element has a macro-optical characteristic and at least one surface. A light shaping surface microstructure (14) is integral on the surface of the optical element. The microstructure homogenizes, shapes and controls directionality of light emanating from the surface of the optical element to produce a smooth, consistent and continuous pattern of light in a predetermined distribution shape and direction. The optical element can either transmit or reflect light incident on a portion of the device and the optical element.

Description

technical field [0001] The present invention relates to the technical field of devices employing optics, and in particular to devices having an optical element having a surface diffuser integral with one surface of the optical element. Background technique [0002] Many devices are known that employ one or more optics such as Fresnel lenses, meniscus lenses, reflective surfaces, polarizers, optical fibers, cylindrical lenses, waveguide filters, grating structures, or other optics. Such devices are increasingly used. These devices apply light from an ambient light source or a beam of light from a light source or a light path from a light source where the light passes through or strikes an optical element in order to alter one or more characteristics of the light. Such devices include, for example, medical diagnostic equipment, lights, chemical analyzers, optical filters, LED displays and devices, microscopes, spectroscopes, and even laser surgery equipment, etc., but are cer...
