Process for making a optical transparency having a diffuse antireflection coating

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 also reduced visibility of surface defects. The includes alternating layers polymerized silicon dioxide titanium on transparent substrate, at least one incorporating discrete particles refractive index different from surrounding polymer. This diffuse reflectance comparable to, or larger than, its still negligible when compared to coating's transmittance. creates loss contrast any reflected image glare, thus masking defects providing comfortable visual appearance. successive are deposited substrate by applying separate solutions an alkoxide, alcohol, water, curing layer elevated temperature before next succeeding applied.
