Band pass filters for the infrared

EURECA offers a range of high-quality interference filters for the infrared spectral range. These filters differ significantly from the standard filters, as sold e.g. by many other companies from catalogues.

The standard size of all interference filters listed below is 25.4mm round (free aperture: > 22mm). On request, these filters can also be supplied in other sizes, as well as in mounts to be screwed onto lenses.

We offer a few hundred basic types with different central wavelengths and half-widths over a spectral range of approx. 1000nm - 11000nm. As a result, normally a suitable filter for the particular application can be found quite quickly. On request, it is also possible to supply filters with slight deviations from the basic specifications within certain limits. If it is also not possible to produce a suitable filter for your application by this, there remains still the possibility of a customer-specific new development, which can make sense already at medium quantities. We are happy to advise you on the exact possibilities.
