Hot Mirror (Heat Reflection Filter)
 

 
UV would destroy the liquid crystal and crisp the plastic parts. IR would cause high thermal energy in the optical engine. Hot mirror is a very good solution to protect the optical or electronic components from damage by reflecting the heat back to the light source. It is designed to minimize the infrared wavelength of spectrum and control specific UV wavelengths while transmitting the visible light.
