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.

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. 

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.
