Self-Centering Jaw Clamps are ideal for easily interchanging optics of different diameters in a system while maintaining a constant optical centerline of the system. Mounts are available for either mounting 4mm to 36mm diameter optics (#16-077) or 5mm to 100mm diameter optics (#16-078). The small jaw clamp features both M4 x 0.7 and 8-32 tapped mounting holes, while the large jaw clamp features both M6 x 1.0 and ¼”-20 tapped mounting holes. The stainless-steel tipped jaws feature a v-groove to help vertical alignment of thinner optics. Self-Centering Jaw Clamps are directly mountable to TECHSPEC® Stainless Steel Mounting Posts and Pedestal Posts.
