Key properties
     Benefits
   
6 transmission profiles in
visible and infrared range
  • Various design options and effects on visible light (transparent, diffusing, blocking)
  • Transparency for LEDs (except 712-8)
  • IR-A & IR-B filter function (724-8 & 712-8)
  • Good thermal insulation properties due to low transmission for IR radiation (712-8 & 724-8)
High transmission for infrared radiation from 800nm – 4500 nm
  • Excellent transparency for infrared heat, especially for 2 mm & 3 mm material thicknesses
  • Good match with IR heating elements

Transmission

The transmission values are measured for a polished sample of a specific thickness.
This graph is based on data from individual measurements. Deviations may result from manufacturing process.
Typical transmission graph of different ceramization states with sample thickness of approximately 4 mm.
