Hot and Cold Mirrors

Hot Mirrors: A hot mirror is designed to reflect infrared light while transmitting visible light. This is useful in applications where heat needs to be directed away from sensitive components or where only the visible light is desired. For example, in high-power lighting systems, hot mirrors can reflect the IR light that generates heat, preventing damage to light sources and other optical components. They are also used in photography and cinematography to block IR light that can cause unwanted heating of camera lenses and sensors.

Cold Mirrors: a cold mirror is designed to reflect visible light while transmitting infrared light. This is beneficial in applications where it is important to allow heat to pass through, such as in illuminated displays or certain types of optical sensors. Cold mirrors are commonly used in stage lighting, where they reflect visible light onto the scene while allowing the heat from the light source to pass through. This helps to keep the stage cooler and prevents overheating of lighting equipment.
