Bandpass filters are used to filter narrow spectral ranges. They only permit light at the defined operating wavelength to pass through and suppress the rest of the light. Jenoptik develops and manufactures these filters, and customizes them to meet your precise requirements. This is achieved using such methods as our ion-assisted coating technology.

In production, we primarily use coatings made from hard oxides that are extremely durable. Softer materials, such as semiconductors, sulfides and fluorides, may also be used depending on the application area. The bandpass filters are usually made from specially arranged packages of interference coatings. They are combined with other coating systems, optical filters or other absorbent materials in order to achieve the required spectral function.
