Abstract
For the determination of the scatter behavior of materials with different aggregate states such as solid components, liquids and particles an Angle Resolved Scatter (ARS) measurement set-up has been developed at LZH. The set-up can be operated in conjunction with different laser sources and arc lamps. Spectral investigations in the range from the DUV to the NIR can be performed by using a monochromator and filters. Mappings are possible by moving of the test specimens in two spatial directions. In this paper, we present result on efficiency measurements for holographic gratings in the visible spectral range. The spatial transfer functions of transmittive gratings are measured very precisely at 633nm. Also, scatter characteristic of nano and micro particles in liquids as well as the scatter distribution of some functional dielectric coated samples are discussed.
