Mini Clamping Fork
  • Compatible with Ø12 mm optical post with base series;
  • Waist-type slot length: 16 mm;
  • Clamping diameter: 14.2 mm;
  • 5-piece package available;

The mini clamping fork from LBTEK has a clamping diameter of Ø14.2 mm and is typically used with Ø12 mm optical posts with base or Ø6 mm flexible post holders. Its three-point contact provides stable clamping force, and the integrated design ensures high rigidity. The PHA-16B3 and PHA-16B4 are constructed from black-anodized 6061-T6 aluminum alloy, while the PHA-16S is fabricated from precipitation-hardened 316L stainless steel to deliver uniform clamping force. The PHA-16B3, PHA-16B4, and PHA-16S are compatible with M3, M4, and M6 socket head cap screws respectively. The 16 mm waist-shaped slot enables 360° rotation around the base for convenient selection of mounting holes. Each clamping fork includes a spacer on the bottom surface to enhance stability when securing posts or post holders with corresponding socket head cap screws. Note: Applying excessive tightening force may induce surface deformation on optical tables, potentially resulting in component misalignment and stability degradation.

The PHA series clamping forks are suitable for fixing Ø12 mm optical posts with bases.

Ø6 mm Flexible Post Holder with Base
  • Base-type design for holder clamping fork;
  • With 360° rotation flexible clamping block for fixing post;
  • Ultra-wide square groove, dual-line contact prevents optical post sliding;

The Ø6 mm flexible post holder from LBTEK features a 360° rotatable flexible clamp block, enabling installation or removal of set screws from any direction when mounting two posts side-by-side. First, secure the vertical displacement of the post, then lock the rotation of the flexible clamp block, enabling fine adjustment of rotation after height fixation. Once the set screw is fully tightened, the flexible clamping block becomes non-rotatable. For height adjustment, the holder base incorporates a through-hole that post allows full bottom through-access, meeting minimum beam height requirements.
