• True Gimbal Design
• Maximum Optic Thickness: 0.25" (6.4 mm)
• Mounts Ø1" (25.4 mm) Optics
• Fine Adjustment Provides ±15° at 1°/rev
• Fully Lockable Design
• Superior Kinematic Performance Without Crosstalk

GMB1 optic mount, which is designed to hold Ø1" (Ø25.4 mm) optics up to 0.25" (6.4 mm) thick, features true gimbal motion in order to eliminate crosstalk when steering a beam of light. The point of rotation for both axes is located at the center of the mounted optic’s surface. Utilizing locking thumbscrews and fine pitch adjusters, the GMB1 offers both coarse adjustment and fine tuning.The coarse adjustment allows 360° of manual positioning for both angular degrees of freedom. The fine adjustment allows for ±15° of control, with rotation of the control knob yielding 1° of angular displacement per revolution. The yaw can be adjusted in a similar fashion using the thumbscrew and setscrew closest to the post. After the desired pitch and yaw position is established, the entire mount can be easily locked into place by tightening both thumbscrews and both setscrews.

• True Gimbal Design
• Maximum Optic Thickness: 0.63" (16 mm)
• GM100 - Mounts Ø1" (25.4 mm) Optics
• GM200 - Mounts Ø2" (50.8 mm) Optics
• Designed for Intra-Cavity Use
• Angular Range of ±2.5° (GM100) or ±2.0° (GM200)
• Graduated Adjuster Knobs (50 Divisions per Revolution)

Thorlabs' Gimbal Mirror Mounts are designed for intra-cavity use, and incorporate a true gimbal design that locates the optical surface directly on the axis of rotation. The design provides pure rotational motion without angular or positional crosstalk.

Two adjustment knobs (graduated with 50 divisions per revolution) are located on the top surface of the mount, making them easily accessible even if the mount is integrated into an optical cavity. They provide excellent angular positioning performance. The GM100 is designed to hold Ø1" (Ø25.4 mm) optics, while the GM200 is meant for Ø2" (Ø50.8 mm) optics. The mounts are SM1- (1.035"-40) or SM2-threaded (2.035"-40), respectively, for compatibility with our lens tubes and accessories, and each mount includes a retaining ring for securing the optic.

• True Gimbal Design
• Maximum Optic Thickness: 0.24" (6 mm)
• Mounts Ø1" Optics
• Compatible with Thorlabs' 30 mm Cage System
• Full 360º Rotation of Optic Holder
• ±30º Rotation on the Optic Holder Saddle

The KC45D Turret Mount is designed to allow a Ø1" optic to be rotated about a point in the center of a 30 mm cage assembly with true gimbal motion. The optic holder is free to rotate through 360º. Once its coarse angular orientation is set, the fine adjustment mechanism (i.e., two 100 TPI adjusters offering an adjustment per revolution of 13 mrad/rev) can be used for precise alignment, using the HKTS-5/64 hex key thumbscrew or any other 5/64" hex key or balldriver. The second angular degree of freedom is achieved by rotation of an intermediate saddle. This saddle connects the optic holder to the cage assembly and is free to rotate ±30º.The optic is secured against the back lip of the SM1 (1.035"-40) center tapped region using the included SM1RR Retaining Ring.
