Alluxa is an ISO 9001:2015 certified, ITAR registered manufacturer of high-performance optical filters and thin-film coatings. Alluxa's technology is based on SIRRUS™ Plasma Deposition process. 

Alluxa ULTRA Series optical filters and thin-film coatings are designed with your application and system requirements in mind. They are all rigorously tested to ensure the highest possible performance and quality for each filter type, and all are designed and specified to exceed the performance of any comparable optical filters on the market.

Optical Filters

Flow Cytometry Filters

Used across a variety of biological disciplines, fluorescence-based flow cytometers rapidly and accurately quantify cells and cellular components. As one of the most important components of these systems, flow cytometry filters must be specifically designed to maximize signal-to-noise ratios while minimizing crosstalk between fluorophores.

LIDAR Filters

Arguably the most versatile active remote sensing technique, LIDAR (Light Detection and Ranging) is used across platforms and across disciplines.

Fluorescence Optical Filter Sets

ULTRA Series multiband filters can be designed with over 10 transmission bands, greater than OD8 blocking between bands, steep edges, and up to 98% transmission. 

Custom and OEM Optical Filters

Are you looking for non-standard spectral shapes, unusual coating materials, tunable filters, extreme blocking, or have other challenging technical specifications for your filter? We'll be able to quickly and efficiently produce bespoke thin films that will allow your system to reach its full potential in terms of both performance and cost.

Bandpass Optical Filters

Through a combination of precision wavelength control, ultra-steep edges, deep blocking, and the industry's highest transmission levels, Alluxa’s ULTRA Series of hard-coated, thin-film optical bandpass filters will optimise the performance of a variety of instruments.

Narrow Bandpass Optical Filters

With the narrowest bandwidths and highest transmission in the industry, Alluxa’s thin-film, ultra-narrow bandpass filters will optimise the performance of laser based systems.

Notch Optical Filters

The deep blocking, tight wavelength control, steep edges, and wide-range transmission of ULTRA Series thin-film notch filters all allow for precision blocking of lasers or other light sources, without sacrificing the quality of target signals.

Dichroic Beamsplitters

The steep edges, maximum transmission, and maximum reflection of ULTRA Series thin-film dichroic filters all translate into minimal loss of light intensity and optimal instrument performance.

Soft Coating Replacement Filters

Alluxa offers a series of hard-coated optical filters that deliver increased performance and durability over traditional soft-coated filters, at comparable prices.

Laser Optics

Dielectric Mirrors

Alluxa's ULTRA Series of high-reflectivity dielectric mirrors provide close to 100% reflection over a broad or precise range of wavelengths. Each hard coated, thin-film dielectric mirror is resistant to laser damage and all will boost instrument performance by preserving light source intensity.
