Low power, good reflectivity broadband metal mirror for deep UV through near-IR; 193 - 1200 nm. Designed to achieve > 90% reflectivity at 193 nm, these mirrors use a high density aluminum coating with dielectric overcoat to maximize UV reflectivity and durability, while maintaining > 85% average reflectivity for 400 - 1200 nm.
PLEASE NOTE: Due to the hydroscopic nature of these mirrors, they are sensitive to high moisture levels. It is recommended that they be kept in a dry condition or dry box when not in use.
