Abstract
An optical filter device having a polarizing beamsplitter, an achromatic polarization manipulator, and at least one dichroic mirror. The polarization manipulator is arranged optically between a first input/output of the polarizing beamsplitter and the dichroic mirror. The polarization manipulator is also constructed in such a way that it effects a 90-degree rotation of a polarization direction of light which a) exits the polarizing beamsplitter at the first input/output, b) traverses the polarization manipulator, c) is reflected by the dichroic mirror, and d) again traverses the polarization manipulator. The optical filter device can also be used as beamsplitter.
