Advanced Anti-Reflective Coating Service

An optical thin film anti-reflective coating consists of one or more precisely engineered layers of material deposited on a substrate to alter how light reflects and transmits through the surface. By reducing unwanted reflections, AR coatings maximize the transmission of light through optical components. These coatings are essential for improving the performance of lenses, windows, and imaging optics by minimizing energy loss and eliminating ghost images caused by internal reflections. When properly designed, AR coatings can reduce surface reflections from over 36% to less than 0.1%, dramatically improving optical system efficiency.

Andover Corporation delivers superior anti-reflective (AR) coatings by combining advanced deposition technologies with decades of expertise. Our comprehensive in-house capabilities enable us to provide custom AR solutions across an exceptionally broad spectral range, from 193nm to 14μm.
