Optical blanks

Optical blanks are the raw form of material from which a finished optic is made from. Using blanks that are close to the final size saves time and money in finished processing. Our in-house capabilities and on-hand material allow us to process optical blanks in under two weeks.

We stock inventory from all major glass providers: Schott, Ohara, Corning, and Heraeus. Please let us know your—quantity, diameter (or L x W), thickness, and  material selection.
