Compact Cross Correlator - 1’’/25 mm Lens Based

The 3DOptix’s intensity auto-correlator is assembled from three modules: beam splitter module, delay line module, and nonlinear SHG module. The incoming signal is split in a 99221 or 99021 3DOptix beam splitter, then the two beams are delayed in our 99121 delay line module, which separates the beams into two parallel beams with 1.5''/37.5 mm interval. These beams are inserted into a 90712 nonlinear SHG module, which generates the second harmonic 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 separated on the optical table.
