LBTEK Grating Mount Adapter can be installed on a thin-walled Ø1-inch optical adjusting mount, enabling pitch and yaw angle adjustment of the clamped grating. The adapter has a simple structural design: by sliding the clamping blocks at the top and bottom of the adapter, the connecting screws on the back of the clamping blocks slide within the machined slots, allowing adjustment of the height of the clamped grating and rectangular mirror. Tightening the two M3 connecting screws on the back secures the grating and rectangular mirror in position. The adapter employs a three-point mounting mechanism with a fixed base and adjustable top, consisting of two bottom surface contact lines and one top surface planar spring contact.
