UV Cold Mirrors


Typical Applications

  • UV-mirror for a 45° incidence angle
  • Ultraviolet heat and 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 a high transmission in the spectrum of 600–2500 nm are the significant characteristics of the SUV dielectric ultraviolet cold mirrors. These properties make the SUV coating an excellent choice for heat and UV light separation applications. (Please follow this link if you only need a UV mirror without heat transmittance.) The coatings of our SUV's 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.
