Optical Substrates &
Precision Glasses
FUJITOK offers the best selection of optical 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.
Customtomized Optical Substrates
Our precision polishing delivers components that meet the highest performance standards.
We provide a wide selection of fused silica and optical-grade glasses with excellent surface quality and flatness. By choosing from our diverse substrate materials, you can optimize optical windows for wavelength range, pressure resistance, and thermal conductivity.
