High Homogeneity Glass


The superior quality of an optical material is reflected in its homogeneity and, to be even more specific, in an extremely narrow variation range for the entire piece of glass with respect to refractive index. Therefore, the optical glasses that are to be used in high-power laser and astronomical applications especially require extremely high homogeneity.

As part of its broad range of optical glasses, SCHOTT manufactures high-quality glasses up to the homogeneity level H5. In response to increased demand, SCHOTT will now offer its customers short lead times for a wide range of preferred glasses up to the quality level H4 according to customer specification. Some of these glasses are also available as i-Line glasses that combine extremely high refractive index homogeneity and high UV transmittance at 365 nm.
