Transmission-Spectrometer for highly efficient solar glass
The uniformity of the hemispherical transmission in the spectral range from 380 nm to 1600 or 2200 nm of coated glass – anti-reflective, anti-soiling, solar protective -, is an important issue for R&D and quality assurance.

The TRANSSPEC is designed for accurate measurements of glass with structured surfaces or scattering properties, especially. Angular dependent measurements between 0° and 70° can be performed optionally.
