Fairhaven, MA 6/12/00 - Nye Optical Products announced the availablity of a hand-held cartridge dispenser designed to take the guess work out of
mixing two-part curing optical gels. The dispenser is ideal for prototyping and other small-quantity applications.
Optical gels, also known as index-matching gels, are used in electro-optic devices to optimize light transmission between engineered plastics and
glasses. Unlike epoxies, optical gels form pliable mechanical connections between rigid parts. Curing gels typically are preferred in applications
where the optical gel has to be wicked into a tight space because, unlike non-curing gels, they are very lo-viscosity fluids before cure. When mixed with a chemically reactive
thickener, the viscosity of the optical fluid gradually increases in place to a gel consistency, which can range from gelatin to hard rubber depending on the formulation required. While high-speed
dispensing sytems automatically combine the thickener and optical fluid in precise ratios, accurate mixing of small quantities of curing gels by hand has always been difficult.
Nye’s cartridge dispenser is designed especially for high-clarity optical gels to ensure thorough mixing and to prevent air bubble entrainment in these manual, small quantity applications. The
reusable dispenser holds a 50 cc Nye cartridge. When the cartridge is inserted into the dispenser, depressing the plunger mixes and applies the two components in the proper ratio. Two standard
curing gel products with refractive indices of 1.46 or 1.51 are available.
