Anti-Reflective Coating

Maximizing Transmission, Minimizing Reflection

Advanced Anti-Reflective Coating Services

Maximizing Transmission, Minimizing Reflection From the UV to Far-IR

Andover Corporation specializes in providing high-quality anti-reflective (AR) coatings that significantly reduce surface reflections and enhance light transmission through optical components. Our AR 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.

Utilizing advanced deposition technologies such as magnetron sputtering, ion-assisted e-beam deposition, and resistance evaporation, we offer custom AR solutions across a broad spectral range, from 193nm to 15μm. Our coatings are applied to a variety of substrates, including BK-7, fused silica, germanium, silicon, sapphire, and more.

  • Reflection reduction to less than 0.1% at angles up to 50°

  • Broad wavelength coverage from UV to far-IR

  • Durable coatings with environmental stability

  • Custom solutions with typical lead times of 4-6 weeks
