16 mm coaxial system alignment plate

The LBTEK 16 mm coaxial system alignment plate is a quick-embedded beam alignment tool with a through-hole at the center, providing convenience for beam alignment and simplifying the optical path collimation process. In beam focusing applications, its central through-hole facilitates viewing the position of the focused spot, where the beam at the focal point can usually pass directly through the hole. By sliding the plate back and forth along the coaxial rod, the spot position can be observed to determine whether the optical path is coaxial with the system.
