Abstract

Metal-dielectric multiple-band high-reflection coatings are designed as induced filters and fabricated by reactive deposition. ${\mathrm{T}\mathrm{a}}_2{\mathrm{O}}_5$ and ${\mathrm{S}\mathrm{i}\mathrm{O}}_2$ are used as high- and low-refractive-index layers, and Cr and Al are used as bonding and reflective layers, respectively, for constructing the filters. The metal-dielectric coatings are deposited on a light-shaping flexible plastic substrate for use as a screen with high-contrast enhancement performance. This screen was suitable for miniprojectors with red, green, and blue LEDs as light sources. Mechanical properties such as stress, hardness, and adhesive strength of these multilayer films are investigated also.
