Abstract:
1. An optical system for polarization-dependent, time-resolved optical spectroscopy, comprising: a polarization device which has a crystal polarizer and comprising a light entry area which is arranged upstream of the polarization device and which is formed in such a way as to enclose a spatial acceptance angle of the crystal polarizer; a light exit area which is arranged downstream of the polarization device, wherein an intermediate area which connects the light entry area, and the light exit area is formed in the polarization device with a path length of at most approximately 4 mm which has to be traversed in the crystal polarizer by light impinging within the spatial acceptance angle; and wherein the path length which has to be traversed in the crystal polarizer is formed in the region of overlapping corner areas of crystal wedges of the crystal polarizer.
