The beam-splitter for the ZP stage is fixed to the ZP-Z stage and so the laser beam's contact point travels along the outer reference mirror when the ZP-Z stage moves. 3. The J/K interferometer mirrors attached to the ZP and sample stages are glued into fixed positions with no possible adjustments in order to reduce size and weight. +| ![Interferometer_Schematic.svg](uploads/76677416d91bb6052882bbc0a687a685/Interferometer_Schematic.svg) | +|:--:| +| Figure 1.

Render of the interferometer parts in SOPHIE. | + In this design the virtual drift is determined by the long reference mirrors in the upstream, lower corners of the vacuum chamber. The initial mirror alignment involved setting the reference mirror parallel to the corresponding mirror mounted on the ZP stage. - - ![SOPHIE_interferometer](uploads/43bfb17f3f46e87154275bf1e8b9672b/SOPHIE_interferometer.png) - ## Fixing the SOPHIE Alignment +
