AR Coating Technology
Anti-Reflection (AR) coatings, also known as anti-reflective films, are specialized optical coatings applied to glass surfaces to enhance light transmission. By leveraging interference effects created by multiple dielectric layers, AR coatings minimize reflected light and maximize transmitted light intensity. This results in improved image clarity for optical systems.
Dinghongrun provides custom AR coating solutions including:
- Standard AR coatings
- Hybrid AR + DLC (Diamond-Like Carbon) coatings
Core Technologies
1. Standard AR Coatings
- Reduces/eliminates surface reflections on lenses, prisms, and mirrors
- Minimizes stray light in optical systems
- Available for:
- Visible spectrum (400-700nm)
- Near-IR (700-1300nm)
- Far-IR (8-12μm)
- Applications: Laser systems, fiber optics, precision instruments
