Mirror Mount, ULTIMA®, Clear Edge, 3.0 in., 2 Locking Knobs
Model: U300-A2K
Product Series Overview
ULTIMA® Clear Edge Mirror MountsThe U300-A2K ULTIMA® Clear Quadrant Mirror Mount offers unsurpassed functionality. This optical mount for 3 inch (76.2 mm) diameter optics includes two 100 TPI locking actuators with knob providing ±3.55° of tip/tilt adjustment. Thick front and rear plates and optimized, stiff springs improve the long-term stability and provide greater protection against vibrations. 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. 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 Adjustment Screws
ULTIMA Clear Edge Performance Mirror Mounts feature a Flexure Lock built with an AJS bushing in select models. Flexure Locks exert a tangential force on the screw to prevent rotation and prevent unintended adjustment.
Replaceable Actuators
The ULTIMA's industry-standard clamp design 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.
