Cold mirror
Cold mirrors perform the opposite function of hot mirrors — they reflect visible light while transmitting infrared radiation. This makes them ideal for applications that require high-quality visible light output without the accompanying heat, such as fiber optic illumination systems, endoscopic lighting, semiconductor inspection equipment, stage lighting and thermal imaging applications.
By separating visible light from the thermal IR component, cold mirrors protect heat-sensitive targets and maintain stable operating temperatures in precision instruments. With durable dielectric coatings that offer high reflectivity across the visible spectrum and excellent IR transmission, they are a reliable solution for any system where thermal isolation and optical performance must coexist.
