The Windows Group has a complete set of instruments designed to characterize the detailed radiometric and optical properties of solar energy materials and in particular glazing and shading materials for windows.

• Optical spectrocscopy (300-2,500 nm).
• Variable-angle spectral ellipsometry (300-1,700 nm).
• In-plane angle-resolved scattering (300-2,500 nm).
• Thermal emissivity.
