Posts provide a simple means for mounting optical components. These posts are 1/2 inch in diameter and incorporate precision machined features which make them more convenient to use. Half inch diameter stainless steel posts are machined with a 1/4-20 or M6 female thread on one end and an 8-32 or M4 female thread on the other. They may be stud mounted to a wide variety of component holders. A 4mm clearance hole through the middle of the post provides for the use of a torque bar for tightening. Post collars are offered separately to hold the posts at a preset height. Post holders are made from aluminum and are equipped with a spring loaded clamp screw to hold the post in position. The base of the post holders is fitted with a 1/4-20 or M6 female thread for attachment to a variety of bases. An adjustable height post holder provides 10mm of vertical adjustment which is actuated by the rotation of a knurled ring.
