Laser Beam Expander Mounts (Industrial Grade)

LBTEK Laser Beam Expander Mount with four adjustment axes, capable of adjusting pitch/yaw angles and X/Y-axis linear translation. It features highly elastic double-hook tension springs and a unique locking mechanism, providing long-term stability for optical systems and equipment. The mount is equipped with four double-hook tension springs (0.8 mm wire diameter), each providing 23 N of tension at the pitch/yaw balance position. The floating front plate includes two M3 locking screw holes; after angle adjustment, a 2.5 mm hex key can be used to tighten the locking screws for long-term stability. The pitch/yaw adjustment employs a single stainless steel plate to limit relative freedom between the front and back plates, allowing for the mounting of heavier optical components, e.g., large-aperture laser beam expanders, with enhanced stability. For X/Y-axis linear translation adjustment, a centering locking knob is added to secure the central moving structure directly after adjustment. Both sides of the mount feature M6 threaded holes for expandable posts in free-space applications. Additionally, LBTEK offers various mounting flanges, including threaded flanges (M22×0.75 mm, M30×1.0 mm, M34×0.10 mm) and smooth-bore flanges (Ø40.5 mm, Ø30 mm, Ø25.4 mm, Ø12.7 mm) for compatibility with diverse optical components.
