Mirror Mount, ULTIMA^®, Center, 1.0 in. Diameter, No Actuators

The U100-AC ULTIMA^® Aperture Base Precision Kinematic Optical Mount uses spring-loaded pawls to gently, but securely, hold high precision 1 inch (25.4 mm) diameter optics from the back against three points on the front plate of the mount. Wavefront distortion in the optic is minimized because the forces acting on the optic are axial, instead of radial and are more distributed. For applications requiring secure mounting, the pawls can be tightened further, compressing the springs, and clamping the optic between the three points on the front plate and the pawls.

Like all ULTIMA mounts, thick front and rear plates and optimized, stiff springs improve the long-term stability and provide greater protection against vibrations. This base model does not include actuators. various actuators can be quickly changed to accommodate a broad selection of adjustment screws, micrometers, and motorized actuators. ULTIMA Precision Kinematic Optical Mounts minimize mount-induced wavefront distortion. Side set screw mounting, found in most optical mounts, is fine for many applications but our tests have shown that this technique induces wavefront distortion in the optic if the set screw is tightened a little too much. Convenient clearance mounting holes on each of two sides are compatible with either 8-32 or M4 screws providing quicker, more precise, and more secure mounting.
