Andover Corporation was established in 1976 with the purpose of designing and manufacturing high-quality optical filters and coatings. Over the years as the company has grown, the focus has remained on quality. Their current facility spans 44,000 square feet on 17 acres of land in Salem, NH.
Andover's facility is custom-designed and state-of-the-art, and includes automated coating, glass polishing, and fabrication equipment. Their testing capabilities are extensive, including both automated spectrophotometers for broadband spectral measurements, and ultra-high-resolution spectrophotometers for narrowband measurements. Their optical metrology lab features a custom-designed, computer-controlled tunable interferometer to measure transmitted wavefronts beyond the capabilities of a traditional laser interferometer.
The company manufactures filters and coatings for a wide variety of applications, including medical instrumentation, fluorescence studies, machine vision, astronomical observation, telecommunications, space-borne systems and defense systems.
Andover is 100% US-owned, and is ISO 9001:2008, AS 9100:2009, AS9104A and ITAR registered.
