Why optical filters from DELTA Light and Optics?

Our thin film components are ultra-hard-coated single glass constructions, offering very high mechanical and spectral stability, low autofluorescence and minimal optical deflection.

The coatings are shift-free in most environmental conditions and can be made on coloured or uncoloured glass as desired.

Our design and manufacturing methods result in coatings with very high transmission, steep edges and deep broad-banded blocking.
