The absorptive and refractive properties of additively colored glasses containing an absorptive metallic silver phase and a separated silver halide phase are altered by irradiating the colored glasses with visible light. Polarization effects and multicolored images can be produced.

Colored, dichroic, birefringent glass articles produced by optical

Silver halide-containing photochromic glasses are rendered optically anisotropic by darkening with actinic radiation and irradiating with linearly polarized bleaching light. A photochromic glass so treated will be optically isotropic when it returns to the clear state, but may again become optically anisotropic when redarkened. Color adaptation results when darkened silver halide-containing photochromic glasses are irradiated with colored optical bleaching light.

Photochromic glasses exhibiting dichroism, birefringence and color

A solar simulator comprising an SnO.sub.2 -containing glass ultraviolet absorption filter in combination with a xenon arc light source, which simulator closely approximates the characteristics of the terrestrial solar spectrum at violet and ultraviolet wavelengths, is described.
