ULTIMA® G Series Gimbal Mounts have a radically simple way of providing stable gimbaled tilting without blocking the beam path. Conventional gimbal mounts tend to be too large and complex to allow high precision true gimbal motion. As a result, they are usually expensive. Even competing kinematic gimbal mounts fall short because their back plate blocks the beam path. The ULTIMA-G has a simple patented design, allowing cost-effective, true gimbal movement with a clear aperture, perfect for beam splitting applications.
What makes the ULTIMA-G unique? It is the only kinematic gimbal mount which holds the optic surface at the center of a hollow hemisphere. Rotation of the sphere results in pure tilt at the optic center without blocking the beam path. That means your beam will go exactly where you expect, without being blocked or having to make iterative adjustments of the axes. The optic mounts from the rear so that the optical surface is at the plane of rotation, regardless of the optic thickness.
Like all ULTIMA mounts, thick front and rear plates and optimized, stiff springs improve the long-term stability and provide greater protection against vibrations. 1 and 2 in. (25.4 and 50.8 mm) mounts are provided with high precision, 100 TPI adjustment screws, or you can use the base model and select the actuators of your choice separately (see ULTIMA Actuators). The actuators can be quickly changed to accommodate a broad selection of adjustment screws, micrometers, and motorized actuators.
The U50-G optical mounts for 0.5 in. (12.7 mm) diameter optics have integral, hex head adjustment screws with optional patented locking mechanisms. The optional KD.37 knobs have two slots for an Allen wrench to increase the adjustment sensitivity.
Slotted mounting holes on two sides are compatible with either 8-32 or M4 screws for convenient mounting.
The optic surface is mounted at the center of a sphere. Rotation of the sphere results in pure tilt without translation at the center of the optic.
