The LBTEK 30 mm coaxial system alignment plate is a rapid 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 typically pass directly through the hole. By sliding the plate back and forth along the coaxial rod in the optical path, users can observe the spot position to determine whether the optical path is coaxial with the system. LBTEK offers special surface treatment processes and customized size services. For inquiries, please contact technical support.
