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.

Bandpass Filters

Bandpass filters are characterized by a high transmitting band that is blocked in the subsequent long-wave and short-wave spectral range.

Depending on the spectral width of the transmitting band, a distinction is made between broadband and narrowband filters.

Bandpass filters can be manufactured with a variety of performance characteristics ranging from the simplest Fabry-PĂ©rot design with a single cavity and unblocked to more complex, fully blocked dielectric designs with multiple cavities and a single substrate.

Application

  • Spectroradiometry
  • Medical Diagnostics
  • Chemical analytics
  • Colorimetry
  • Astronomy
  • Areas where spectral separation is required

Properties

  • Use of hard, dielectric oxide layers
  • Wavelengths from UV, VISIBLE, NIR to FIR
  • Excellent blocking outside bandpass
  • Maximum possible transmission
  • Excellent temperature resistance
  • Excellent durability, even under demanding climatic conditions
