Optical Gels

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, although not water soluble, is made to “disperse” when immersed in water to facilitate cleaning. Code 0608 was designed not to “disperse” in water for applications where water immersion without dispersing or changing is required.

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.
