Surfaceprocessing

Economic, precise, of highest quality

Surface processing for optical components made of quartz glass is divided mainly on the basis of surface roughness, flatness and parallelism. Achievable tolerances are ≤ 1 μm.

These parameters are customer-specific and to be defined respectively for each application. A crucial factor are the process requirements that form the basis for the surface of the quartz glass parts and their respective criteria.

We do not shine on the surface only

By highest quality requirements, certified processing and process steps, professional expertise and reliability we achieve precise surfaces of our quartz glass parts.

Surface quality:

At present according to DIN ISO standard 10110 (P3). However, varying customer-specific surface qualities are possible, see example (P4).
