Technical Description
(1) The Ø12mm optical connecting rod is a basic component required for constructing many rigid structures, with multiple length specifications available ranging from 30mm to 100mm. The precision-ground stainless steel connecting rod is made of 304 stainless steel and is compatible with our connecting rod brackets and structural accessories.

(2) The top of the PCA-A Series connecting rod is equipped with a non-detachable M6 stud with a height of 5mm. The end of the connecting rod is provided with an M6 threaded hole with a depth of 13mm. There is a Ø3mm through hole on the side of the connecting rod, through which a ball-head screwdriver or wrench can pass to provide greater torque when tightening components.

(3) Application Schematic:

Stainless steel connecting rods are available in different lengths, providing an irreplaceable role in the adjustment of free-space optical experiments and manual optical path calibration, and can be used to install various optical-mechanical components arbitrarily.
