Low-E glass emissitivity measurement

IR reflection set-up for measurements according to EN673 ( thermal emissivity of coated glazing )

Schematic drawing of the reflectance set-up for large panes ( side view ), showing one of the two large sample supports. These supports are height adjustable to adjust the alignment.

The accessory kit with laser alignment system enables reflectance measurements at an angle of 6 degrees, from small 5 mm samples to large square meter size samples.

The system includes :

  • FTIR spectrophotometer
  • IR reflectance accessory.
  • 5 gold coated reference mirrors are provided which guarantee traceability of the measurements to international standards.
  • All the necessary procedures for measurements and calibration are provided along a software for data processing and calculations.
