Specialized Infrared Coatings & Filters

Photonics MarketplaceAndover Infrared CoatingsUtilizing various coating technologies (such as magnetron sputtering and electron beam with ion assist) Andover Corporation specializes in infrared coatings from the near IR out to 14μm. Constructed of hard, durable firstsurface dielectric coatings, our infrared products will withstand cleaning and handling associated with any high-quality optical component.

Andover offers custom infrared optical coatings on a variety of substrates, in various shapes and sizes. While generally operating at 0º to 45º, the coatings can be optimized for any particular angle or range of angles of incidence. Some of our custom infrared optical coatings include dual-band IRs, dichroic beamsplitters, ultra-narrowband IR filters, antireflection and broadband antireflection coatings.

Andover's IR neutral density filters exhibit outstanding spectral neutrality, outperforming all others on the market. Employing metallic coatings on highquality Germanium substrates, these ND filters utilize a combination of absorption and reflection to provide a specific attenuation value from 2 - 14μm.

Andover can design and fabricate longwave pass filters to suit your particular requirements. Our IR longwave pass filters provide a sharp cut-off below a particular wavelength. Often used for order sorting, they isolate broad regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy.

We have an abundance of in-house testing and measuring capabilities specifically for the infrared region and can provide documentation for performance and traceability. We are AS9100 as well as ISO9001 certified. Every phase of the process is performed in-house, including thin-film design, mechanical design, substrate fabrication and coating, inspection, and environmental testing. We coat a variety of substrate materials, including Germanium, Sapphire, Silicon, Zinc Sulfide, and Zinc Selenide.
