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.

Edge Filters

Edge filters separate a broad spectrum of light into two components: a transmitted and a blocked component.

These filters are defined by either a cut-on or a cut-off slope, which provides the transition between a high blocking region and a high transmission region. Cut-on and cut-off edges are typically defined by long wave or short wave pass filter coatings.


  • Versatile
  • Analyzers for clinical chemistry
  • Various process controls, e.g. during grain harvest


  • High edge steepness
  • High blocking and transmission
  • High temperature stability
  • Cut-on / cut-off wavelengths from 400 nm to 1000 nm
  • Blocking up to DUV (long pass filter) or 1200 nm (short pass filter)
