NIR cut filter



Coated filter glass (volume filter) with an anti-reflection layer according to ISO 9211. This combination of an absorption filter glass and interference filter coatings ideally combines the two filter technologies.


  • The right glass for any application can be chosen from a large portfolio of different volume filters. Filters can thus be produced in different thicknesses.
  • The maximum diameter of the substrate is  200 nm.
  • The coating is particularly dense and resistant. It permanently protects glass from moisture corrosion.

Additional functions

On special request we can add the following functions to the filter:
  • Extended protection against abrasion.
