Ultra-Broadband Metallic Mirror

Coating Options
Avantier offers three metallic coatings for mirrors, each with distinct spectral properties:
- Aluminum: General-purpose with high reflectance in the visible range.
- Silver: High reflectivity in the visible and near-infrared regions.
- Gold: Ideal for infrared (IR) applications beyond 2 microns.

These mirrors are made with a reflective metal film and a dielectric overcoat, which protects the metal and enhances reflectivity.
