  | DICHROIC GLASS-is produced in optics laboratories. Extremely thin layers of metal oxides-such as titanium, selenium, and tin are deposited onto clear glass in a vacuum chamber. This coating reflects certain wave-lengths of light and allows other to pass through. The glass changes color when viewed from different angles due to laws of light refraction. The color is determined by the thickness of the coating as well as the material used. When seen from a different thickness of coating, thus producing a different color. Dichroic Glass has many uses in aerospace industry, photography, and optics. The technology is called "Thin Film Physics." |
