Cold Mirrors
Cold Mirrors
Cold Mirrors represent Andover Corporation's solution for separating visible and infrared light, effectively reflecting visible wavelengths while transmitting infrared energy.
These specialized mirrors feature first-surface coatings deposited on low-expansion borosilicate glass substrates, optimized for 45° angle of incidence in randomly polarized light.
This design makes them particularly effective for heat management in high-intensity illumination systems, providing excellent performance and durability in demanding applications.
