(8.0s) Edmund Optics designs and manufactures sputtered thin-film interference filters from prototype quantities to volume production. Filter substrates can be coated through different methods. High-volume magnetron sputtering benefits from excellent cost-effectiveness and efficiency, while our highest-performance filter coatings for demanding systems are deposited through ion beam sputtering.

(1.5s) Coated filter wafers may be cored or cut into smaller pieces, and laser engraving labels filter mounts with key details. Automated assembly helps place filters in those mounts more efficiently. Inline and post-process metrology, including a suite of commercial and proprietary spectrophotometers, maintain high levels of quality and part-to-part consistency.

(1.2s) Our filters can be found in a large variety of optical applications, ranging from fluorescence microscopy to flow cytometry, qPCR to spectroscopy, and many more. Edmund Optics engineers and coding designers can guide you through sourcing the right filters and other optics.

We look forward to finding the best solution for your system. What can we make for you? visit our website or contact our product support team to get started. (3.7s)

Life Cycle of an Optical Filter

Optical filters selectively pass or block certain wavelengths of light and are critical for optical applications ranging from fluorescence microscopy, to flow cytometry, to spectroscopy. Edmund Optics® designs and manufactures hard-coated optical filters in our Akita, Japan Factory.

Follow along as we go through a day in the life of an optical filter, moving through coating, processing, and metrology.

We make a wide range of optical filter types including bandpass, notch, longpass, shortpass, dichroic, and more. Our engineers can design and manufacture build-to-print or fully custom solutions for your optical application.
