Hot mirror

Hot mirrors are designed to reflect infrared radiation while transmitting visible light, making them essential for managing thermal load in optical systems. They are widely used in projection systems, lighting fixtures, thermal management, medical lighting, and industrial illumination where heat-sensitive components must be protected from IR radiation. 

By redirecting infrared energy away from the optical path, hot mirrors prevent image distortion, reduce thermal drift, and extend the lifespan of delicate components such as LCD panels, sensors, and polymer optics. Available with custom coating designs for specific cutoff wavelengths, they deliver high visible transmission (>90%) and strong IR reflection (>95%) to ensure both optical clarity and effective thermal management.
