Spectral filters for glass surfaces The emissivity of glass is determined by wavelength regions in which electromagnetic radiation:

a. mostly passes through the material (transmission)

b. is almost totally absorbed (absorption)

The temperature is best measured inside the absorption bands, as glass is impenetrable to infrared radiation in these regions.

Wavelength region for surface temperature measurements:

• 5.14 μm for glass thicknesses of 1 mm and more, at medium to high temperatures

• 7.75 μm for glass thicknesses less than 1 mm at low to medium temperatures

Spectral responses around 3.9 μm and 1 μm will enable you to measure temperatures with a glass-specific penetration depth (depending on material).
