Filters

Precision optical filters since 1969, from UV to NIR. We specialize in custom filters from prototype to OEM quantities. Fluorescence, astronomy, and overrun filters in stock. Prototyping, engineering, and high-volume production utilizing plasma-assisted reactive magnetron sputtering, e-beam, thermal evaporation, and ion assist. ISO 9001:2015 Certified.

Design and manufacture advanced custom thin-film components for OEM volume applications. Products include linear variable filters, variable dichroics, high-quality fluorescence filter sets, filters and dichroics, and filter sets for point-of-care instruments, beamsplitter cubes, and many other components.

Designer and manufacturer of interference filters: narrow and broad bandpass, long- and shortwave, ND filters, atmospheric windows, AR and metallic coatings. Holographic diffraction gratings: plano, concave and blazed, pulse compression/stretcher gratings. WDM and telecom applications include diode laser tuning gratings and network communications gratings.

Produces high-performance optical coatings and components specializing in the design, development, and manufacture of ion-beam sputtered, low optical loss, laser-damage resistant thin films for the UV-VIS-IR spectral region. Applications include lasers, laser devices, nonlinear crystals, medical instruments, and other photonic devices.

Manufacturer of thin-film pellicles for use as beamsplitters, beam combiners, attenuators, filters, and optical windows. Standard items, uncoated and coated, are available from inventory; special frames, coatings, flatness, transmission and documentation are available for custom applications.
