LBTEK offers a wide range of coaxial mounting plates designed for mounting Ø25.4 mm optical components, lens tubes, or collimated LED light sources. Both rectangular and round shapes are available. The round version can be mounted into mechanical parts with SM2 internal threads or Ø50.8 mm clear apertures, featuring a central SM1-threaded through hole. The rectangular version can be directly inserted into the coaxial system, with three thickness options of 4 mm, 9 mm, and 12.5 mm. Center options include SM05, SM1, and RMS threads or Ø25.4 mm, 30.5 mm, and 32 mm clear apertures. All coaxial plates come with four coaxial rod through-holes compatible with the 30 mm coaxial system, allowing free sliding along the rods. Each through-hole is equipped with an M3 or M4 locking screw, which can be tightened using a 1.5 mm or 2 mm hex key.
