Interferometer e.g. Michelson interferometer, has optical plate movably supported by solid body joints so that beam splitter and reflection mirrors are movable relatively to each other with solid geometrical adjustment of reflection mirrors

摘要

#CMT# #/CMT# The interferometer has a beam splitter (1) for dividing a beam of light (L1) i.e. coherent beam of light. Produced partial beams (L2, L3) are overlaid again by reflection mirrors (2, 3), and an intensity of another beam of light (L4) is analyzed with a detector. The reflection mirrors are arranged jointly on an optical plate (4). The optical plate is movably supported by solid body joints (7-10) so that the beam splitter and the reflection mirrors are movable relatively to each other with solid geometrical adjustment of the reflection mirrors. #CMT#USE : #/CMT# Interferometer e.g. Fourier spectrometer such as Michelson interferometer. #CMT#ADVANTAGE : #/CMT# The optical plate is movably supported by the solid body joints so that the beam splitter and the reflection mirrors are movable relatively to each other with solid geometrical adjustment of the reflection mirrors, thus achieving a highly precise deflection of the reflection mirrors and the beam splitter with reduced constructional costs. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an interferometer with adjusted mirrors.
