Important information for customers from the EU

Please note that the Principality of Liechtenstein is not a member of the EU. For this reason, the following points must be observed:

TVA – Value Added Tax

Our prices are exclusive of VAT and will be shipped as such. I.e. concretely, you have to pay the value added tax (TVA) when importing into your country (an EU country). You can reclaim these taxes from your state.

Customs clearance – EORI number required

All companies need a so-called EORI number (Economic Operator’s Registration and Identification) to import from non-EU countries. This number is used for your identification as well as for the automated customs clearance, i.e. for the import into your country (an EU country).

The respective national issuing office of the EORI number can be found on the website of the European Union. In Germany and Austria, the EORI number is assigned by customs.

Dielectric Mirrors

Compared to metal mirrors, dielectric interference mirrors are spectrally less wide and their reflection is angle-dependent. However, they can achieve reflection values in the visible range of more than 99.9% at a vertical angle of incidence.

This is possible because optically high-quality, low-loss interference layer systems are manufactured from pure, absorption-free materials using state-of-the-art coating technology under clean room conditions.


  • Highly reflective and semi-transparent reflectors for the optimal setup of various laser systems
  • Components for laser experiments in chemistry, physics and metrology
  • Various lighting equipment
  • Optic devices


  • Suitable for wide wavelength ranges from 220 – 3’000 nm
  • Suitable for high laser power
  • Suitable for angles of incidence from 0° to 45
  • High thermal resistance (up to 550°C with quartz glass or sapphire substrates)
  • Long-term stable layers, independent of environmental influences
  • Extremely durable layers
