ULTIMA® Series Low Distortion Six-Point Mirror Mounts

Product catalog summary

Overview: The ULTIMA® Series Precision Kinematic Optical Mounts are designed to minimize wavefront distortion induced by the mount itself. Unlike traditional side set screw mounting, which can cause distortion if over-tightened, these mounts use spring-loaded pawls to secure optics gently and securely.

Key Features:

Minimizes mount-induced wavefront distortion by applying axial forces instead of radial.
Spring-loaded pawls gently clamp optics, with the option to tighten for enhanced security.
Constructed with thick plates and extra-stiff springs for long-term stability.
Quick-change actuators for ease of use.

Specifications:

Available in various aperture sizes: 1 in., 2 in., 3 in., and 4 in.
Each model can be equipped with 2 or 3 actuators, providing different levels of adjustment precision.
Adjustment screw thread: 100 TPI knob with angular range up to ±5°.
Translation of optics is achieved by turning all three actuators.

Model Variants:

U100-AC Series: 1 in. aperture, available with 2 or 3 actuators.
U200-AC Series: 2 in. aperture, available with 2 or 3 actuators.
U300-AC Series: 3 in. aperture, available with 2 or 3 actuators.
U400-AC Series: 4 in. aperture, available with 2 or 3 actuators.

Additional Information: Larger aperture versions (5 in. and 6 in.) are available upon special request. The mounts are compatible with various optical components and can be customized with different actuator configurations.

ULTIMA® Series Precision Kinematic Optical Mounts U400-AC2K U300-AC2K U200-AC2K U100-AC2K 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. ULTIMA-AC optical mounts use spring-loaded pawls to gently, but securely, hold high precision 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. • Minimizes mount-induced wavefront distortion • Spring-loaded pawls gently clamp optics in the mount • Thick plates and extra-stiff springs for long-term stability • Quick-change actuators Spring Loaded Pawls Optics Mount’s Face Plate Center Line Spring-loaded pawls are used to hold the optic to minimize the wavefront distortion or can be clamped to provide enhanced security.
