Mirror Mount, ULTIMA®, Clear Edge, 1.0 in, 3 Locking Allen-Keys

The U100-A3H ULTIMA® Clear Quadrant Mirror Mount offers unsurpassed functionality. Thick front and rear plates and optimized, stiff springs improve the long-term stability and provide greater protection against vibrations. The patented clear quadrant design exposes the edge of the optic, allowing beams to pass close to the edge of a mounted optic. The actuators can be quickly changed to accommodate a broad selection of adjustment screws, micrometers, and motorized actuators. Hard carbide pads enable smooth, repeatable motion. A large array of optical mounting accessories is available for these mounts making ULTIMA a basic building block for many optical systems. This optical mount for 1 inch (25.4 mm) diameter optics includes three 100 TPI locking hex actuators providing ±7° of tip/tilt adjustment. Translation of the optic is accomplished by turning all three actuators. 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. ULTIMA mounts can be mounted to posts for adjustable height or pedestal posts for a stable fixed height.
The Clear Edge Advantage
With the Clear Edge design, beams can be reflected from one mount to another at smaller incident angles (Φ) taking less space between the mounts (d). Clear Edge Mounts are also ideal for compensating for pulse dispersion effects through multiple reflections on Chirped Mirrors.
Locking Hex Adjustment Screws
ULTIMA Clear Edge Hex-Driven Mirror Mounts feature Allen-key adjustments to save space and prevent unintended adjustment. For long-term stability, Flexure lock is included in select models. The flexure lock built in the mount body, used for U50-AL and U50-AL1 models, and the flexure lock integrated in the adjuster’s bushing, used in U100 and U200 models, exert a tangential force on the adjustment screw to prevent rotation. Both adjustment and locking actions are accomplished using a single tool from the same side of the mount.
Replaceable Actuators
The ULTIMA's industry-standard clamp design (excluding the U50 models) allows many different types of actuators to be used to adjust the mirror position to meet the requirements for any application. Actuators can be replaced with ease by simply loosening two screws to allow the actuator to gently slide into and out of the mount. ULTIMA mounts are compatible not only with standard knob and hex-key adjustment screws, but also with micrometers and motorized actuators.
