Ohara optical glass serves as the cornerstone of advanced optical systems and is widely used in digital devices, such as digital cameras, cellular camera phones, and LCD projectors. Our leading edge materials are also used in optical devices such as microscopes and astronomical telescopes.
For many years we have been mindful of the environment through the development and manufacture of our ecologically safe glass types, currently melting more than 130 environmentally safe glass types that are free of both lead and arsenic. Ohara produces more than 300 tons of high quality optical glass each month available as strip, slab, cut blanks, pressings and other forms.

Ohara i-Line High Homogeneity Glass
These 14 glass types have excellent internal transmittance in the near UV (>98% at i-line, 365 nm) and are solarization resistant. They can be produced in large sizes with outstanding homogeneity values
(+/- 0.5 x 10-6). These glasses are ideally suited for use in semiconductor optics (stepper cameras and illumination systems) and astronomical optics (spectragraph cameras, etc.)

Ohara Low Softening Temperature Optical Glass
Ohara's Low Softening Temperature Optical Glasses are a series of glasses that have been developed to be molded at lower temperatures than our conventional optical glasses, while maintaining the same general optical properties (refractive indices, dispersions, etc.). These glasses are environmentally safe as they do not contain PbO and As2O3 in their composition and they allow for a simplified waste stream disposal.
The Low Softening Temperature Optical Glasses are used for Ohara's Fine Gobs for molding operations and help to extend the life of the mold pressing tools by minimizing the reaction between the softened glass and the mold materials. The Low Softening Temperature Optical Glasses types are available in strip form, blanks or Fine Gobs.
