Spectral Transmittance Measurement For Glass

Measure how glass transmits light across defined wavelength ranges.

What is spectral transmittance?


Spectral transmittance describes how much light passes through glass at different wavelengths.
Unlike a single light transmission value, spectral measurement shows how glass performs across a wider wavelength range.

This is important for photovoltaic glass, coated glass, architectural glass and other functional glass products.

Why transmittance matters


Small differences in transmittance can affect product performance, coating quality and customer acceptance.

For photovoltaic glass, transmittance is closely related to energy performance.
For coated and processed glass, spectral data helps verify whether the product meets required optical characteristics.

Common inspection challenge


Basic light transmission testing may not provide enough information for advanced glass products.

When coatings, treatments or functional layers are involved, manufacturers often need more detailed spectral data to compare samples, track process changes and verify product performance.

How LUARI supports transmittance measurement


LUARI BTG-8S support spectral transmittance measurement for glass manufacturers, testing laboratories and quality control teams.

The systems are designed for practical glass sample testing and can support defined wavelength-range measurement for PV glass, coated glass and processed glass applications.
