Abstract
New composites useful for infrared transmitting applications comprise a dispersion of small particles of diamonds in a matrix having infrared transmission properties (from about 1 to at least 10 .mu.m wavelength) and refractive index substantially similar to that of diamond. The composites exhibit mechanical toughness and durability 2-4 times that of the similarly treated matrix alone without adverse effect on optical properties.
