The C1011(/M) and C1045(/M) Ø1" (Ø25 mm) Post Mounting Clamps are an integral part of our Ø1" Post Assemblies, providing a rigid, general-purpose mounting surface. These mounting clamps can be used for fastening our wide array of optomechanical mounts in much the same way breadboards are commonly used. We also offer a horizontal mounting bracket. The clamping mechanism is directly compatible with our Ø1" (Ø25 mm) RS-Series Posts. Vertical positioning is achieved by sliding the rear clamping mechanism along the length of the Ø1" (Ø25 mm) post. Once the desired vertical position is achieved, the clamping mechanism is actuated by turning the included quick-release handle. A ratchet-style mechanism allows the rotation of the handle to be adjusted without tightening or loosening the clamp: pull the handle outwards to disengage it and rotate it to a more convenient position. Quick-release handles are also offered separately below in case a replacement is needed. The RSHA(/M) Adjustable Height Collar, also sold below, acts as a fine height adjuster with up to 0.20'' (5.1 mm) of vertical adjustment, has a resolution of 0.025" (0.64 mm) per revolution of the actuator ring, and is compatible with our Ø1'' (Ø25.0 mm) posts.

Thorlabs' C1011(/M) Post Mounting Clamp features a removable 2.00" x 2.00" (50.8 mm x 50.8 mm) front plate that provides a variety of tapped holes and counterbores (see the drawing to the right). The included 1.44" (36.5 mm) long quick-release handle allows the clamp to be easily secured to Ø1" (25 mm) posts. Turning the handle engages a 1/4"-20 (M6 x 1.0) threaded stud to actuate the clamping mechanism. An internal ratchet-type mechanism allows for the handle's rotational position to be adjusted without tighening or loosening the clamp. Additional handles can be purchased separately below. ![]() ![]() Click for Details C1045(/M) Front Plate.

Thorlabs' C1045(/M) Post Mounting Clamp features a removable 3.50" x 3.50" (87.5 mm x 87.5 mm) front plate that provides a variety of tapped holes and counterbores (see the drawing to the right). The included 1.44" (36.5 mm) long quick-release handle allows the clamp to be easily secured to Ø1" (25 mm) posts.

The C10QR(/M) Quick-Release Handle, included with the Ø1" post clamps above, is also offered separately. In many cases a cap screw is used to lock a flexure-based clamp in place on a post, which requires a balldriver for adjustments. Depending on the mounted load, using a balldriver can be difficult, or even unsafe. This quick-release handle mitigates this problem by allowing the clamp to be hand-tightened, ensuring better control over the amount of torque applied to tighten or loosen the clamp. This also decreases the amount of time needed for basic setup and alignment by eliminating the need for additional balldrivers and allowing for a quick way to secure a clamp. Once installed, rotating the 1.44" (36.5 mm) long handle engages a 1/4"-20 (M6 x 1.0) threaded stud to tighten or loosen the clamp. The internal ratchet-type mechanism allows for the handle's rotational position to be adjusted without actuating the mounting stud. Simply pull the handle outwards to disengage it from the mounting stud, as shown in the image to the right, then rotate it to a more convenient position. This feature ensures that the handle will always be accessible to the user. ![]()
The RSHA(/M) Adjustable Height Collar for Ø1" (25.0 mm) Posts offers convenient height adjustment for post mounted hardware. An easy-to-access actuator ring allows fine height adjustment at 0.025" (0.64 mm) per revolution. This collar also allows components to be freely rotated without changing height. To use, slip the collar over a Ø1" (Ø25.0 mm) post and hold at the desired height. Tighten the 1/4"-20 (M6) cap screw to secure the collar's position on the post via the flexure clamp. Place an optomechanic around the post on top of the collar and twist the actuator ring to adjust the component's height. The height can be fixed by turning the attached slotted locking ring, which includes four slots that can be used with our SPW504 Spanner Wrench. The nylon ring on top of the collar prevents marring while adjusting the height. | |||||||||||||||||
