Tunable Michelson Interferometer (91220)

The 3DOptix’s tunable Michelson interferometer is assembled from three modules: beam splitter module, delay line module, and a beam-splitter/combiner module. The incoming signal is split in a 99221 or 99021 beam splitter module, then the two beams are delayed in a 99122 delay line module, which separates the beams into two parallel beams with 3''/75 mm interval. These beams are inserted into a 99002 mirror reflection module outputs exactly on the 3Doptix grid, allowing an easy and accurate alignment. Due to the fact that all elements are exactly on the 3D grid, the three modules can be easily assembled together or can be separated on the optical table.
