SIGMAKOKI D-TOP Base Plate

This is a base plate for fixing the Φ20mm post stand. By loosening the split clamp slightly, you can replace the holder without changing the position or change the optical axis height. It is also possible to correct the mounting position of the kinematic mirror holder (MHG-MP20-NL/MP25-NL/MP30-NL) and the offset (20mm) to the mirror surface. The center of the cube beam splitter (NPCH) or polarizing beam splitter (PBS) can be placed on the optical axis (line of taps on the base). The oblong mounting holes (2.6mm shift) can be used to fine-tune the position of the optical element and correct the optical axis misalignment. Since the post stand is fixed with a split clamp, the optical element can be fixed in any horizontal direction. If you fix the screw on the slotted hole on the split clamp side, the MHG will be installed with a 20mm offset. The split clamp is made to be firm to maintain accuracy. Tighten the post stand securely until it cannot be rotated. There are four mounting holes, but please fix one of the slotted clamp sides without tightening the screw. For this reason, only three mounting screws are included.
