Thorlabs' Standard SM-Threaded Kinematic Mounts are designed for stress-free mounting of thin optical components. These mounts have an internally threaded hole with a lip on the back side against which the optic can be secured using the included externally threaded retaining ring.

These mounts offer an angular adjustment range of ±4° (±3° for the KM200T) and are mountable in left- or right-handed orientations. With #8 (M4) counterbored through holes on the back plate, these mounts are compatible with both imperial and metric Ø1/2" posts. The knobs on the KM100T and KM200T are removable, thereby exposing the hex sockets at the end of the lead screws (see the video to the right).

Thorlabs offers a variety of other two and three adjuster mirror mounts including our high-stability Polaris^® Mirror Mounts.
