Dielectric Mirrors
Dielectric Mirrors offer near total reflection, minimizing losses in nearly all optical systems. These coatings are very durable, easily cleaned, and resistant to laser damage.

Available either broadband or narrowband, they operate efficiently over 0–45° angle of incidence: AOI=0°, R>99.8%; AOI=45°, R>99.5% (Rs>99.9%, Rp>99.2%).
