1 Quartz Glass for Optics Data and Properties

2 Quartz Glass for Optics Data and Properties = 3D material, optically isotropic. In quartz glass, the homogeneity is typically specified in one direction only. Heraeus manufactures quartz glass grades, which are controlled and specified in all 3 directions regarding striae, homogeneity and stress induced birefringence, for the most demanding applications. These materials are identified by the 3D symbol. 1 For raw formed ingots the bubble specification is valid for the area defined by the minimum diameter tolerance. For machined parts it is defined as 1 % of the material. 2 Bubbles or inclusions.8 mm diameter are not counted. For Suprasil 311/312 and Suprasil 1/2 a specification for bubbles and inclusions of 1µm is possible on request. 3 For non-spherical bubbles the diameter is averaged. 4 The Dn value is the maximum permissible lateral variation in refractive index (measured by interferometer at 32.8 after subtraction of tilt and offset) over 9% of the diameter or edge length of a fine ground piece, or 8% of a raw formed ingot. The maximum test diameter is 4 mm. Larger pieces are measured using overlapping interferograms. 5 Does not apply to drawn rods. Lower values available on request. 7 The residual strain values refer to the measured phase difference per cm light path. The residual strain value is specified over 9% of the diameter or edge length of a fine ground piece, or 8% of a raw formed ingot. n. sp. = not specified Refractive index at C and 1 bar The given values are interpolated from measured values having an accuracy of ± In contrast to other optical glasses, quartz glass shows very little difference in refractive index from melt to melt. *without Suprasil 1, 2, Grade Bubbles and Inclusions Homogeneity Residual Strain Fluorescence OH-Content The bubble grade is given for every 1 cm 3. 4 Dn-value Quartzglass from Heraeus is free of inclusions.

3 Optical Homogeneity The false colour interferogram below shows the typical two-dimensional refraction-index distribution. The interferogram belongs to a circular blank. The sectional view along the diameter shows the refraction-index distribution across the blank. One can clearly see the very low value in the center of the plate and the rise close to the edge.
