     The collimator adapters with SM1 threads developed by OMTOOLS are applicable for the adaption of Ø9 to Ø18 collimators with SM1 mounts, lens tubes and cage components. The adapters are designed with SM1 external threads and central limit holes, and the latter are applicable for our retaining ring wrench. Designed with precision-machined extra wide relief groove, the adapters provide stable two-line contact with collimators, with the help of two screws with plastic caps. The black anodic oxidation for the entire adapter minimizes the impact on the optical system by reducing surface reflection.
