Glass | Solutions for Low-E Glass Tempering

Necessity of Referencing

All kinds of glass, coated and uncoated, change their emissivity behavior in dependency of the angle of view. Especially low-E coatings show an unusual behavior. For a reliable and reproducible temperature measurement a referencing from underneath (uncoated glass surface) is necessary.

Process temperature: 50 °C (122 °F) to 600 °C (1112 °F)


  • Compact bottom up system for coating independent underneath measurement
  • Integrated ultra-fast glass breakage detection combined with Digitally controlled lens protection system (DCLP)
  • Pre-assembled system for easy installation on glass tempering furnaces
  • Glass area calculation
