Optical Interference Filters

Coating Equipment for Precision Optical Components

Optical interference filters—such as bandpass, dichroic, polarizing, notch filters, and beam splitters—must meet demanding requirements: minimal optical losses, ideally no absorption or scattering, high transmission in the passband, deep blocking in the stopband, and steep, well‑defined filter edges.

As the performance of cameras, projectors, telescopes, and optical measurement systems continues to advance, the need for standardized components with superior interference coatings grows accordingly.

These multilayer coatings define the function of each component. They can reflect light, split it into partial beams, block specific wavelengths, or act as precise pass filters for selected spectral ranges.

We provide coating systems engineered specifically for these high‑performance filter applications.
