Understanding AR (Anti-Reflective) Coating Technology
How AR Coating Works
When light hits an uncoated optical surface, approximately 4-5% reflects at each air-glass interface, resulting in significant optical losses. AR coatings work by:
- Destructive Interference – Multiple thin film layers are engineered so that reflected light waves cancel each other out
- Refractive Index Matching – Each layer is designed with specific optical properties to minimize impedance mismatch
- Wavelength Optimization – Coating thickness and materials are precisely calculated for target wavelength performance
This technology allows optical systems to achieve 99%+ light transmission efficiency, dramatically improving image quality, brightness, and overall system performance.

Anti-reflective Coating FAQS
What is an Anti-Reflective (AR) coating?
An AR coating is a multi-layer thin film applied to optical surfaces to reduce reflection and improve transmission. By precisely controlling refractive indices and layer thicknesses, AR coatings minimize optical losses at specific wavelengths or across broad spectral ranges.
What is the difference between broadband AR and V-coat AR?
Broadband AR: Low reflection across a wide spectral band.
V-coat AR: Extremely low reflection at a specific wavelength (e.g., 325 nm, 532 nm, 850 nm, 1550 nm).
Broadband is ideal for imaging; V-coat is ideal for lasers and monochromatic systems.
Can you coat both sides of a substrate?
Yes. Most AR applications require double-side coating, and we ensure precise alignment and uniformity on both surfaces.
Can you provide coating performance testing?
Yes. We supply:
Spectral transmission curves
Reflectance data
Environmental durability results
Coating thickness measurements
Surface quality inspection
Complete optical reporting can be provided for regulated or mission-critical projects.
Do you design custom AR stacks for OEM production?
Absolutely. We offer full custom stack design, simulation, prototyping, and volume manufacturing support, including documentation and batch consistency control.
