Optical Substrates & Precision Glasses

FUJITOK offers the best selection of opticcal substrates and precision glasses for use in a wide spectrum of optical applications. With two subsidiary workshops specializing in polishing and cutting, we deliver substrates of superb surface quality and flatness at a highly competitive cost. Contact us for more about optical substrates and glasses we offer.

Fused Silica

Thanks to its excellent engineering properties like exceptionally high thermal shock resistance and near zero thermal expansion, Fused Silica is the right substrate for temperature insensitive optical component supports and optical parts used in highly variable temperature regimes, such as lenses and mirrors.
