The LBTEK 30 mm Sliding Coaxial Plate consists of two coaxial plates: one fixed in free space or a 30 mm coaxial system, and the other movable through a dovetail structure with a travel range of ±6 mm.
One side of the sliding plate has four coaxial blind holes (coaxial rods cannot pass through), and the other side has M3 threaded holes for mounting coaxial rods with M3 setscrews. The fixed plate features a central SM1-threaded through-hole for mounting Ø25.4 mm optics up to 3.5 mm thick, secured with the included SM1R retaining ring.
The bottom has an M4 threaded hole for connection to optical posts. The plate is engraved with ±6 mm graduations for manual positioning, and locking is achieved by tightening the top M3 screw. All adjustments are made using a 2 mm hex key.
Important Note: Do not remove the three M2 screws or the top M3 screw, as doing so may cause the ball bearings to fall out.
