Abstract:

An optical coupling fluid which is transmissive to light, is a polymerized (cured) gel prepared from a mixture of two silicon components, one a silicon oil and one a silicon gel. The miscible substances can be combined to provide a composition suitable for preparation of a thin film between the optical components which then polymerizes to form the gel without danger of leakage. The transmissive characteristics are excellent, and coupling material does not become opaque to short wavelengths under use conditions.
