Features

  • Integrate SM-Threaded Components into Our Double-Bored Optic Mounts
  • Available with Either Internal or External SM Threads

The adapters offered on this page are designed to enable SM05, SM1, or SM2 lens tube systems to be directly fitted into our standard double-bored Ø1/2", Ø1", or Ø2" mounts, respectively. These are ideal for forming a simple quick-release mount: by simply releasing the setscrew on the mount, a lens tube assembly can be easily removed and reinserted into any of our standard double-bored kinematic mounts.
