     The OMTZ series of 60 mm coaxial 3-axis right-angle mounts has been widely applied in the adjustment of optical elements installed at 45° on a horizontal level. The ports are equipped with SM2 threaded holes and four M3 threaded holes with a pitch of 60x60 mm or φ6 unthreaded holes. The unthreaded holes are provided with M3 set screws on the side for fixation. The mount is compatible with 60 mm cage systems. The mounts feature optimized structural design, precision machining and assembling, and high stability and sensibility. The three thread pairs consist of carobronze bushings and stainless steel screws, providing ±4° degrees of smooth regulation. Two of them are provided with dismountable knobs, and the third one must be adjusted with the 2 mm hexagon wrench. Three M4 threaded holes are arranged on the both sides of the mount, which allows its direct connection with Ø12 mm stainless steel optical posts or Ø25 mm cylindrical posts. In addition to 60 mm coaxial 3-axis right-angle mounts, we also provide 30 mm coaxial 3-axis right-angle mounts.
