The U50-A ULTIMA® 1/2 inch (12.7 mm) diameter, Clear Quadrant Mirror Mount offers unsurpassed functionality. Thick, hard-anodized 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 three hex-keyactuators have an 80-TPI thread pitch and provide ±5° pitch/yaw adjustment with 3.8 mm of axial transalation. Translation is accomplished by turning all three actuators the same amount. A large array of optical mounting accessories is available for these mounts making ULTIMA a basic building block for many optical systems. The optional KD.37 knobs have a 5/64" hex key to fit in the adjustment screws. An Allen wrench can be used to increase the adjustment sensitivity. 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
Left: Flexure lock built in the adjuster’s bushing. Right: Flexure lock built in the mount body
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. See our Recommended Compatible Actuators in the Accessories section below.
Extra Thick Frame
ULTIMA mounts have extra thick frames for optimal stiffness and exceptional stability. The additional stiffness lowers deflection during adjustment, allowing fast and easy alignment.
