andover corporationWith over 40 years of experience, Andover Corporation is a recognized world leader in the manufacture of high-quality optical coatings and optical filters. We have an extensive line of standard/catalog products including bandpass, ND, long- and short-pass, and heat-control filters, available in sizes of 12.5mm, 25mm and 50mm diameter.  We manufacture a broad array of custom components in wavelengths from UV to Mid IR. Our optical coating deposition techniques include ion-assisted e-beam deposition (IAD), magnetron sputtering, and resistance evaporation. Some applications include airborne surveillance and targeting, defense/military & aerospace, spaceborne and ground-based astronomy, machine vision, photolithography, agricultural imaging, hyperspectral imaging, water and gas analysis, calibration and more.

Andover has years of experience working with various substrates and materials.  We stock a variety of optical-quality infrared-transmitting substrates such as silicon, sapphire, germanium, zinc sulfide, zinc selenide, water-free fused silica and calcium fluoride.  All substrates are optically polished and of high optical quality.  We also stock a large selection of Schott colored filter glasses, as well as quartz and borosilicate glass.

Andover Corporation specializes in infrared coatings from the near infrared out to 14µm.  Constructed of hard, durable first-surface dielectric coatings, on optical-quality infrared substrates, our products will withstand cleaning and handling associated with any high-quality optical component.  We have an abundance of in-house testing and measuring capabilities specifically for the infrared region and can provide documentation for performance and traceability.  

Andover Corporation has the capabilities, knowhow, and desire to solve the simplest to the most complicated coating requests.  With multiple coating technologies and in-house value-added services at our disposal, we have the unique ability to flexibly combine these technologies to create advantageous, competitively priced solutions for our customers.  With our unsurpassed quality in product and customer service, our competitive advantage is our reliability. We are ISO9100 & AS9100 Aerospace certified.
