JNS Glass & Coatings offers several different products for reflecting, passing and absorbing heat.   Most of these products can be categorized under hot mirrors and cold mirrors.  A hot mirror is a specialized dielectric mirror, a dichroic filter, often employed to protect optical systems by reflecting infrared light back into a light source, while allowing visible light to pass.  JNS Glass & Coatings offer several different hot mirror designs.  A cold mirror consists of the same dichroic coating design but does the opposite.  The cold mirror reflects the entire visible light spectrum while very efficiently transmitting infrared wavelengths.

JNS Glass, Glass For Lighting

Hot Mirrors, also known as short wave pass filters, are designed to reflect infrared, and in some cases UV radiation, while transmitting visible light.   Coatings can be designed for varying angles of incidence.

Typical features of our Hot Mirrors include:

  • High transmission for the visible light range
  • Up to 24” diameter on any thickness
  • High reflection of infrared
  • Utilize high quality borosilicate glass substrates – SCHOTT Borofloat®
  • Thin film dielectric multi-layer coating
  • Standard angles of incidence are 0 and 45 degrees
