PLP series stainless steel pillar posts are designed to construct rigid structures in various heights. Diameter of the pillar post is 25mm with precision ground finish. Both ends of the pillar post are tapped suitable for M6 screw. A 3.6mm diameter hole is provided on the surface of the post for providing extra torque while tightening components on it. We can use 3.5mm allen key or a screwdriver with less than 3.6mm diameter for tightening. By using pedestal adapter PPA-PG-12D and pedestal fork PF 25 we can fix the pillar post to the base plate. Pedestal shims can be used to raise height with 0.1mm increment while setting up optical experiments.
