Abstract
A process for producing an object which has optical layers comprising the steps of applying optical layers to a substrate of plastic material wherein the optical layers are applied by means of a chemical plasma-impulse vaporization process (PICVD).
Claims8
A reflector, comprising:
- a concave-shaped substrate consisting essentially of a plastic material which is temperature-stable up to at least 100° C.;
- and
- a reflecting surface on said substrate constructed as a cold-light mirror consisting essentially of a plurality of layers of different refraction coefficients applied to said substrate by means of one of:
- a plasma impulse (Pi) process, a chemical vaporization process (CVD) and a phase-impulse chemical vaporization process (PLCVD).
