HOT MIRRORS

Hot Mirrors perform as their name states: they reflect the heat and transmit the visible light. All of the coatings are classified as hard, first-surface dielectric, and will meet or exceed the specified humidity and abrasion specifications. To prevent cracking or crazing from high heat applications, all coatings are deposited onto a low-expansion material such as borosilicate glass.

BENEFITS 
  • Transmits visible wavelengths and reflects near-IR heat generating wavelengths
  • Prevents cracking or crazing from high-heat applications
COMMON APPLICATIONS
  • Projection systems
  • Photocopiers
  • Surgical and dental lighting
  • Film and photographic apparatus
  • Illumination systems
  • Scientific instruments
