Reflector-prism system for natural or artificial light for intended spatial zones - has one-piece combination of reflection, transmission and diffraction units made from transparent glass or plastics material
摘要
The mirrored reflecting surface, prisms and/or lens structure are all combined in a single transparent glass or plastics material unit, and cannot be separated from each other. They may be all in line or alternatively may be rotationally symmetric. The mirrored surface is created by an evaporated film process onto the transparent surface in a high vacuum and, by using a template, the ratio of transmitted light to reflected light for the finished surface can be varied. ADVANTAGE - Easily interchangeable one-piece combination of units.
