功能

• Base plate for fixing φ20 mm post stand. It is used when thin elements such as lenses and polarizers are placed close to each other on the optical axis. Up to 3 φ20 mm post stands can be placed at intervals of 64 mm.
• Because the base plate has a bottom, the optical axis height is raised by 5 mm.
• Since the width is 2 mm shorter than the post stand, the base plate does not interfere with the proximity of the elements.
• The post stand is fixed from the side with 1~2 set bolts.
• Set bolts are attached in 4 directions so you can access from any direction.
