91351 Intensity auto-correlator - 1''/25mm Parabolic mirror based



The 3DOptix’s intensity auto-correlator is assembled from three modules: beam splitter module, delay line module, and nonlinear SFG/DFG module. The incoming signals are color-separated in a 99221 or 99021 3DOptix Dichroic splitter, then the two beams are delayed in our 99120 delay line module, which separates them into two parallel beams with 0.5''/12.5 mm interval. These beams are inserted into a 90722 nonlinear SHG module, which generates their sum frequency output 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 easily be assembled together or can be separate on the optical table.
