Plane und planparallele Optiken - Produktgruppe für Laserkommunikation

Plane & Plane-Parallel Optics. High Accuracy for Any Application.

We produce various plane and plane-parallel optics in the highest quality and in the geometries of your choice. In combination with coatings, we offer you a wide spectrum of products, for example mirrors, windows and wedge plates.


Our mirrors are made from low-expansion and very stiff materials, such as quartz glass, ceramics or glass ceramics. These mirrors stand out due to their light weight (mass reduction of up to 90 %) while maintaining the quality of the functional surface.

Windows and wedge plates

We also manufacture windows and wedge plates.

They are characterized by:

  • Lowest roughness
  • Highly precise functional surfaces created using precise correction processes (IBF, MRF)
  • Optics with the lowest surface defects (used for example in laser technology, the semiconductor industry, metrology, medical technology)

You can find information about our coating expertise under Coating Design.
