Hot Mirror

IR Blocking Hot Mirror

A hot mirror reflects infrared (IR) radiation and transmits visible light.  They are typically inserted in the path of the light beam, reflecting the infrared back toward the energy source, and transmitting the cool visible light to the target. Due to the diverse characteristics of different light sources regarding output energy, no single design will provide optimum performance across all applications. EMF can develop a custom hot mirror design by examining your light source and your desired IR reflection.

  • Over 90% transmission in the visible spectrum
  • Reflect over 90% of Infrared (IR)
  • Glass substrate
  • Tight Tolerance (±5nm at 50% transmission)
  • Can be designed for angles other than normal
  • Can be modified to respond to other light source characteristics

  • 26 vacuum coating chambers
  • 40 million in2 of coating capacity for high volume coatings
  • Available in large formats up to 36″
  • Uniform distribution across large deep dish substrates
