Hot Mirrors

Our standard line of high transmission Hot Mirrors are a great choice for preventing undesirable heat from damaging thermally unstable materials or altering the spectral characteristics beyond that position in a light path by reflecting infrared light while allowing visible light to transmit. Two designs are offered for use at either 0° or 45° angle of incidence. These specialized dielectric mirrors are produced on Borosilicate/Float glass. Hot Mirrors may also satisfy your requirements of a dichromatic beam splitter. If other substrate materials are of interest to you, to pass ultraviolet light for instance, please contact us. Custom sizes are easy to process as well.

  • Reflect the infrared light
  • Transmit the visible light
  • Optimized to remove undesirable heat and infrared illumination
  • Available for 0° or 45° angle of incidence
  • High Reflected to Transmitted light performance
