These post-mounted kinematic mirror mounts are designed to house large diameter optics. The C1517 accepts Ø2" (Ø50.8 mm) optics, while the C1518 accepts Ø3" (Ø75 mm) optics. Optics are secured in these mounts by a nylon-tipped setscrew. Both mounts are designed with heavy-duty springs to ensure mechanical stability while supporting the weight of the large diameter optics. Vertical positioning is achieved by sliding the rear clamping mechanism along the length of a Ø1.5" post. Once the desired vertical position is achieved, the clamping mechanism can be actuated using the attached handle.

These clamps feature a quick-release handle for securing the clamp to a post. The handle contains a 1/4"-20 (M6) threaded stud that engages the part by simply rotating the handle. An internal mechanism allows the handle's rotational position to be adjusted without actuating the mounting stud. For users of the previous generation of post mounting clamps, the same quick-release handle is also sold separately (Item # C15QR(/M).
