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. Each ULTRA Series dichroic filter, polychroic filter, dichroic beamsplitter, or beam combiner is resistant to laser damage and can be designed to work at any angle. All are ideal for use in applications such as fluorescence microscopy, flow cytometry, and Raman spectroscopy.

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.
Challenging custom optical filters without prohibitive pricing

At Alluxa, we are continually striving to improve our products by researching and developing novel thin-film technologies. Therefore, we welcome any custom optical filter requests for non-standard spectral shapes, unusual coating materials, tunable filters, extreme blocking, or any other challenging technical specifications.
Durable, hard-coated optical filters for replacing laminated filters
Alluxa offers a series of hard-coated optical filters that deliver increased performance and durability over traditional soft-coated filters, at comparable prices. These soft-coating replacement filters are available with center wavelengths across the visible spectrum with bandwidths typically between 10 nm and 50 nm. All of the hard-coated filters in this series offer both greater than 90% transmission and greater than OD4 blocking at prices that are comparable to laminated filters. Continue reading
