Optical Post Assemblies
  • Post Holders & Clamps

    Description

    Posts (or Rods) provide a simple means for mounting optical components at particular heights from the base. These posts are 1/2 inch (112.7mm) 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 threads on one end and an 8-32 or M4 female threads on the other end. 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 posts (Rods) in position. The base of the post holders are 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. We offer a variety of sizes of post holders matching the posts and they are all available in varying lengths. Cross clamps are used to connect two posts together. The half inch posts may be jointed to each other, or to our 6mm posts. Both fixed perpendicular and rotational clamps are offered. These clamps are the split ring type which provide high clamping force. For ease of use, they are equipped with capstan crews. All types provide strong clamping force.

  • Pedestal Posts

    Description

    Pedestal bases provide a strong and secure method for the mounting of mirrors and other sensitive optics at fixed heights. A range of different component holders can be attached to the top of the pedestal by means of screws. An 8-32 or M4 screw can be threaded directly into the top or bottom of the pedestals. Pedestal heights can be varied to compensate for different beam center-heights within an optical layout. The complete pedestal/mount assembly can then be flexibly attached to a breadboard or optical table by means of a disc or fork clamp (provided with captive screw). Alternatively, a screw or stud may be inserted into the base of the pedestal so that it can be attached directly to a base. The pedestals are made of solid stainless steel for sturdy mounting.
