Optical coupling gel primarily used to match the refractive index of fused Silica and BK-7 glass but can be utilized for other glasses.
Optical Gel Codes 0607 and 0608 are optically and chemically nearly identical, and both are used for coupling optical fibers and other optical components, and for mode stripping. Optical Gel Code 0607 is a thinner gel than 0608 and, upon standing, the surface of 0607 will normally appear to be fluid. Code 0608 appears to be much less fluid.
Application: This profoundly black gel minimizes ghost images caused by secondary reflections off of a lens surface. When the gel is near the refractive index of a glass element, light going through the glass goes into the gel and is trapped by absorption in sub-micron particles of black pigment.
All Cargille Sub-Lux gels are very stable and will not harden, dry out, or evaporate.
