Fused Silica and Quartz Ingots for Optical Applications

Ingots of optical grade fused silica serve as the raw material for more complex optical components.

Our ingots are either sold raw formed (as they come from our forming processes) with a clear aperture of 80% or with a ground surface and 90% clear aperture. The raw formed ingots typically have a wider tolerance.
