The C1510(/M) Compact Post Clamp allows optic mounts with 8-32 (M4) tapped holes to be attached to a Ø1.5" post. Each compact post clamp includes a C15QR(/M) Quick-Release Handle for mounting to a Ø1.5" post; replacement quick-release handles can be purchased separately below. For low-profile applications, the handle can be removed and replaced with a 1/4"-20 (M6) cap screw at least 1/2" (12 mm) long.
Clicking on the image to the right displays a sequence of three images illustrating the mounting procedure using an LMR1 lens mount. The angle of the optic mount can be set in place (see image 1) while the knurled knob is used to thread the device onto the C1510 (see image 2). For final tightening, a 5/64" (2 mm) hex key or ball driver can be inserted into the four holes provided on the knob (see image 3). This enables the user to exert additional torque in the final tightening stage.

The CH1530(/M) and CH1560(/M) Cage Clamps allow 30 mm or 60 mm cage systems, respectively, to be mounted horizontally to our Ø1.5" Posts. The quick-connect mechanism allows for drop-in/drop-out mounting of a cage segment; to secure the cage segment, tighten the hex cap screw on the cage clamping mechanism using a 9/64" (3 mm) hex key or balldriver. Each cage clamp includes a C15QR(/M) Quick-Release Handle for mounting to a Ø1.5" post; additional quick-release handles can be purchased separately below. For low-profile applications, the handle can be removed and replaced with a 1/4"-20 (M6) cap screw at least 1/2" (12 mm) long.
The application to the right shows the CH1530 supporting a cage system composed of 4 ER6 cage rods, an SM1Z Z-Axis Translation Mount, and a CP33T cage plate. This system can be used as a telescope to expand or contract the beam diameter using lenses of appropriate focal length placed in the Z-axis mount and cage plate.
The CV1530(/M) Cage Clamp allows a 30 mm cage system to be mounted vertically to our Ø1.5" Posts. The quick-connect mechanism allows for drop-in/drop-out mounting of a cage segment; to secure the cage segment, tighten the cap screw on the cage clamping mechanism using a 9/64" (3 mm) hex key or balldriver. Each cage clamp includes a C15QR(/M) Quick-Release Handle for mounting to a Ø1.5" post; additional quick-release handles can be purchased separately below. For low-profile applications, the handle can be removed and replaced with a 1/4"-20 (M6) cap screw at least 1/2" (12 mm) long.
The vertical cage clamp can be converted to a horizontal cage clamp. To do so, unscrew the four cap screws on either side of the cage clamps using a 9/64" (3 mm) balldriver or hex key, turn the front plate 90°, and replace the cap screws.
Custom CV1530(/M) Clamp Mounts can be ordered for 16 and 60 mm cage system compatibility. Please contact Tech Support for more information.
The application to the right shows a Ø1" POLARIS-K1 ultra-stable mirror mount attached to an MA4 Post Mounting Adapter using 8-32 (M4) threading. The 1/4" clearance on the MA4 adapter is used to connect to the 1/4"-20 threading of the Ø1.5" post.

The C15QR(/M) Quick-Release Handle provides a simple and reliable way of securing a flexure-based Ø1" (Ø25.0 mm) or Ø1.5" post clamp. 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.
Easily installed by replacing the 1/4"-20 (M6) locking screw in a post clamp, the 2.03" (51.4 mm) long handle contains a 1/4"-20 (M6) threaded stud that engages a part by rotating the handle. Once the handle is tightened to secure a clamp to a post, 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 PSHA(/M) Adjustable Height Ø1.5" Post Collar offers a 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 Ø1.5" 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 locked by tightening the 8-32 setscrew with a 5/64" (2 mm) hex. The nylon ring on top of the collar prevents marring while adjusting the height.
