摘要： A sol-gel process is disclosed for depositing multi-layer antireflection coatings on plastic substrates. One or more polymerized, titanium-containing solutions are provided by mixing a titanium alkoxide, an alcohol, and water, and one or more polymerized, silicon-containing solutions are provided by mixing a silicon alkoxide, an alcohol, and water. These solutions are applied to the plastic substrate in an alternating fashion, to produce a succession of uniform layers of polymerized titanium dioxide and polymerized silicon dioxide. Each layer is individually cured before the next layer is applied. The resulting coating of multiple polymerized layers provides very low reflectance over the entire visible wavelength range, yet with excellent mechanical strength and durability.

摘要： A coated transparency, and method for making it, is disclosed, the transparency having a multi-layer antireflection coating that provides high transmittance with low specular reflectance, yet that also provides reduced visibility of surface defects. The coating includes alternating layers of polymerized silicon dioxide and polymerized titanium dioxide on a transparent substrate, with at least one of the layers incorporating discrete particles having a refractive index different from that of surrounding polymer. This provides the coating with a diffuse reflectance that is comparable to, or larger than, its specular reflectance, yet that still is negligible when compared to the coating's transmittance. The diffuse reflectance creates a loss of contrast for any reflected image or glare, thus masking any surface defects and providing a comfortable visual appearance. The successive layers of the antireflection coating are deposited on the substrate by applying separate solutions of an alkoxide, an alcohol, and water, and by curing the layer at an elevated temperature before the next succeeding layer is applied.

The coating comprises (a) a first coating layer having a high refractive index deposited on the substrate; (b) an epoxide-silica coating layer deposited onto the high refractive index coating layer, comprising an inorganic silica component and an organic organo-silicate component, and (c) a silica coating layer consisting essentially of silica, deposited directly onto the epoxide-silica coating layer. The anti-reflection coating optionally comprises a stack of coating layers, between the first high refractive index coating layer and the epoxide-silica coating layer, having alternating a low refractive index and a high refractive index.

摘要： An encapsulant for use with opto-electronic devices and optical components incorporates a filler made from a glass that has been processed into particle form and heated to a predetermined temperature for a predetermined time, along with an epoxy having an index of refraction matched to that of the glass and heated to a predetermined temperature for a predetermined time, to prevent settling of the filler particles after mixing the filler particles with the epoxy, and thereby obtaining uniform dispersion of the particles within the epoxy. The encapsulant provides for high light transmittance, and its coefficient of thermal expansion can be varied by varying the amount of filler without substantially altering the optical properties of the encapsulant. The coefficient of thermal expansion variation within the encapsulant preferably is less than 30%, due to uniform dispersion of the filler particles within the epoxy.
