SM1-Compatible Kinematic and Gimbal Mounts
Both images above show the F280APC-B fiber collimator mounted in the KM100T kinematic mount using an AD11F adapter. On the left, the KM100T is mounted upwards using the #8 (M4) counterbore accessed by a through hole in the front plate. On the right, the KM100T is mounted with one of two back-located #8 (M4) counterbores, which are orthogonal to the optic mounting bore and to each other.
The KM100T mirror mount uses a retaining ring for stress-free mounting of a thin optical component. An optic is secured in the mounting hole with the included SM1RR SM1 (1.035"-40) threaded retaining ring, which can be attached using the SPW602 spanner wrench. This threading also allows the mount to be compatible with Ø1" lens tubes.
The universal KM100T is compatible with both imperial and metric threaded Ø1/2" mounting posts via #8 (M4) counterbored through holes and can be attached to the post in a right-handed, left-handed, or upward-facing orientation, as shown in the photos to the right. The mount has removable knobs that expose hex sockets in the lead adjuster screws. The KM100T features 1/4"-80 adjusters for tip and tilt adjustments. An optional accessory, the LN2580 bronze locking nut, is available to lock the adjusters once the desired position is reached.
Thin Kinematic Mounts are also suitable for mounting fiber collimators utilizing adapters such as the AD11F, as shown above.
The K5X1 5-Axis Kinematic Optic Mount offers an optic cell that can be adjusted along 5 axes (pitch, yaw, and XYZ), each with a locking screw for stability. The translating cell has SM1 threading (1.035"-40) for attaching Ø1" mounted optics. The cell can also be used to mount Ø1" (Ø25 mm) unmounted optics up to 0.38" (9.5 mm) thick using the included SM1RR Retaining Ring, which can be tightened using an SPW602 or SPW606 Spanner Wrench (sold separately). The mount features engraved vertical and horizontal tick marks to use as an alignment aid for the mounting cell. For post mounting the K5X1 kinematic mount in a right- or left-handed configuration, two orthogonal #8 (M4) counterbores are provided.

For adjustment on all of the axes available with the K5X1 plus rotational adjustment, we offer the K6XS 6-Axis Kinematic Mount (sold below).
The K6XS 6-Axis Kinematic Optic Mount is designed as a general-purpose, high-precision positioner. The optic cell can be translated along 6 axes, and each axis has a locking screw for stability. The translating cell has SM1 (1.035"-40) threading for attaching Ø1" lens tubes or mounting Ø1" (25 mm) optics up to 0.55" (14 mm) thick using the included SM1RR Retaining Ring, which can be tightened using an SPW602 or SPW606 Spanner Wrench (sold separately). The rotating dial has tapped 4-40 holes for attaching the K6A1 (sold separately below).
In testing, the K6XS was shown to drift less than 15 µrad in 48 hours at typical environmental conditions, with a 2 °C temperature fluctuation. The X and Y axes cause less than ±10 µm of crosstalk when translated over their full range.
The KC1-T offers three adjusters with independently locking setscrews. The rugged mechanical design provides excellent stability when mounted in a cage system or on a post.
Both the front and rear plates have been machined with four clearance holes designed for direct compatibility with our 30 mm cage system standards. The rear plate provides locking setscrews to clamp to cage rods for secure positioning. The cage rod holes in the front plate are sufficiently oversized to allow ±4º tip and tilt without interference with the rods. The KC1-T has an SM1 (1.035"-40) center tap for mounting optics and is compatible with our SM1-Series Lens Tubes and related accessories. Two SM1RR Retaining Rings are included with the KC1-T and can be used to mount a Ø1" optic up to 5.5 mm thick. Thicker optics can be mounted by using an SM1-series lens tube.
The 30 mm Right Angle Kinematic Cage Mount mounts an optic in a double-bored adjustment plate for two lines of stable contact and securely holds the optic with a locking nylon-tipped setscrew. The kinematic adjustment plate mounts the optic at a 45° angle with ±4° pitch and yaw adjustment range and is actuated with 100 TPI (Threads Per Inch) adjustment screws for smooth, high sensitivity movement.
The photos above show the KC45D Gimbal mount in different 30 mm cage system configurations.
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.
The GM100 gimbal mount for Ø1" optics is designed for intra-cavity use. 50 divisions per revolution graduated adjustment knobs are located on the top surface of the mount, making them easily accessible even if the mount is integrated into an optical cavity. This design provides pure rotational motion without angular or positional crosstalk.

The minimal profile of the GMB1 Gimbal mount is ideal for crowded optical setups.
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.
