UV Cold Mirrors


Typical Applications

  • UV-mirror for 45° incidence angle
  • Ultraviolet heat / light separation
  • UV-exposure machines
  • Medical technology
  • Sensor filters
  • UV-curing-machines

The coating of our heat-transmitting SUV-ultraviolet front surface mirror consists of 100% dielectric layers. We base the mirror on a heat-resistant borosilicate glass substrate. A high reflection in the range of approximately 350 - 450 nm, and high transmission in the spectrum of 600 - 2.500 nm, are the significant characteristics of the SUV dielectric ultraviolet cold mirrors. These properties make the SUV-coating an excellent choice for heat / UV light separation applications. (If you only need a UV mirror without heat transmittance, please follow this link.) The coatings of our SUV ultraviolet cold mirror offer durable resistance against heat, humidity, and abrasion. We can modify the ultraviolet-mirror layers for other wavelengths and cut-on or cut-off points according to customer specifications.
