Hot mirrors (hot mirrors) are selective mirrors designed for reflect infrared (IR) while transmitting visible light. They enable reduce thermal load in optical systems without compromising brightness.
Applications : video projectors, medical devices, high-intensity lighting systems.
Cold mirrors (cold mirrors) work in a complementary way: they reflect visible light and transmit infrared, to obtain a cool, powerful, stable lighting.
Applications : LED lighting, projection, imaging, optical instruments.
