The ULTRA Series optical filters and coatings are specifically designed to be integrated into the most sophisticated instruments used in biotechnology, remote sensing, telecommunications, chemical engineering, robotics, and a variety of other fields.

Each optical filter or thin-film coating can be custom designed to provide precision transmission, blocking, or reflection at any range of wavelengths from the UV to the IR (~250 nm to ~13 µm). Using state-of-the-art design techniques, our designers meticulously ensure that all requirements are met over the specified AOI range and cone angle of the beam, while taking into account manufacturing tolerance and operating temperature.

ULTRA Series thin-film optical interference filters and coatings are all hard-coated using an innovative plasma deposition process that allows us to achieve precision wavelength control, highly uniform coatings, and industry-leading performance. After coating, all go through a rigorous testing process to guarantee that all spectral and mechanical requirements have been met.

As a result, all ULTRA Series optical filters and coatings are highly durable, thermally stable, and resistant to laser damage. ULTRA Series bandpass filters and notch filters increase system performance through a combination of ultra-steep edges, deep blocking, and the industry’s highest transmission levels. Likewise, our dichroic filters and dielectric mirrors preserve the intensity of any light source by providing broadband or precision reflection and transmission with exceptionally steep transitions between bands.

Whether your system requires extreme flatness, a large AOI tolerance, TWE control, or any other challenging specifications, ULTRA Series optical filters and thin-film coatings can be custom designed and manufactured to exceed these requirements and raise the most advanced instruments to their highest potential.

Quality And Consistency From An Innovative Thin-Film Coating Process

Alluxa thin-film optical filters and dielectric mirrors are all hard-coated using our SIRRUS™ plasma deposition process on equipment that was designed and built by our team. This allows us to reliably and repeatedly produce the same high-performance optical thin films over several different coating runs, which translates to consistent performance across all of your systems.
