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.

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.

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.

Select models are available in both right- and left-handed versions: U100-A2K and U100-A-LH‌-2K, U100-A3K and U100-A-LH‌-3K. They are essentially mirror images of each other to provide flexibility and convenience in optical system setups.

ULTIMA mounts have extra thick frames for optimal stiffness and exceptional stability. The additional stiffness lowers deflection during adjustment, allowing fast and easy alignment. 

ULTIMA Clear Edge Performance Mirror Mounts are available in models with either 100-TPI or 170-TPI adjustment screws. The 100 TPI screws are lockable, which is preferred for applications that require long-term stability. The 170-TPI screws have higher sensitivity, enabling faster and easier alignment, which is ideal for applications that require many adjustments.

Newport offers numerous adapters to substantially broaden the utility and function of the ULTIMA Clear Edge beyond the typical mirror mount function. Mirror Size Adapters enable the use of smaller diameter optics. 45° Mirror Mount Adapters can hold mirrors at a 45° angle to the face of the mount, which is especially useful for constructing a periscope. Fiber Optic Adapters provide compatibility with fiber optic components. And other Specialty Mirror Mount Adapters include components that allow the ULTIMA Clear Edge to hold cube beamsplitters, objective lenses, thin optics, and replicated parabolic mirrors, and to both hold and allow manual rotation of polarizers.
