Optical components made of glass, crystals, glass ceramics and ceramics

3D Glass & Ceramic Components.

Complex Components in Your Design.

We design and manufacture complex rigid 3D structures from thermally and structurally stable vitreous or ceramic materials for a wide variety of OEM applications. We have the ability to design monolithic mounting structures.  Integrating individual optical components, mounting structures and systems into dimensionally and thermally stable monolithic structures has significant performance and cost advantages.


We have a variety of unique and proprietary manufacturing technologies including grinding, honing, die sinking, and etching as well as the ability to exchange design data with you during development.


Technical properties of the materials we use:

  • Thermal characteristics: zero thermal expansion, equal thermal expansion, wide operating temperature ranges,
  • Mechanical characteristics: mechanically rigid, stable,  long lifetime
  • Physical characteristics: low wear, RF resistant, hard material
  • Chemical/biological characteristics: Resistant to climatic changes, high chemical resistance, biocompatible
  • Electrical/magnetic characteristics: insulating, non-conducting, non-magnetic



We are able to manufacture with mechanical tolerances down to the sub-μm range for special applications.

Mechanical supporting structures – equal thermal expansion

Different coefficients of thermal expansion of optical elements and mechanical supporting structures often have a negative effect on optical performance (wave front, focus etc.)  in high-precision and temperature-stablized optical systems. Manufacturing mechanical mountings from the same material as the optics greatly minimizes reciprocal forces and stabilizes performance of the overall system.

Mechanical supporting structures – lowest thermal expansion

The use of ULE (Ultra-Low-Expansion) materials in high-precision and temperature stabilized systems provides high accuracy and stability, even for applications in extreme temperature ranges. Precise processing of amorphous and crystalline materials is one of the areas of expertise we can use to provide highly stable OEM solutions for customer applications.
