Table-top system for light scatter measurement »Albatross-TT«

System description

The new table top system ALBATROSS-TT (3D-Arrangement for Laser Based Transmittance, Reflectance and Optical Scatter measurement – Table Top) enables high sensitive measurements of angle resolved light scattering, reflectance and transmittance of optical and non-optical surfaces, materials and components within the entire 3D-sphere.

Applications
