The 9762-K Tiny Commercial Corner Mirror Mount is ideal for laboratory use as well as for building into your products. This 0.5 inch (12.7 mm) diameter center mount ships with two Allen-key adjustment screws, extra-stiff springs for better long-term stability, and actuator locks. Two 2-56 (M2) through mounting holes per side minimize rotation when you secure the mount. This mount features the smooth adjustability that you expect from our proprietary screw manufacturing process. The unique locking system provides exceptional long-term stability, minimal movement during the actual locking process, and greater protection against vibrations. Using sapphire seats as the bearing surface for our ball-tipped screws ensures durability. In addition, repetitive adjustments won’t leave tracks, so positioning will remain deterministic and precise. You can build these commercial versions of our mounts into your setup and know that once you make an adjustment and lock it down, your setup will stay put. You can’t buy this much stability at a better price anywhere.
With a corner mount, the center of the mirror is intentionally located at the xy intersection of the pitch and yaw adjusters, i.e., at the virtual fourth point of the square formed by the ball points of the three actuators. To achieve gimbal movement, two adjacent adjustment screws must be actuated the exact same distance. For gimbal pitch adjustment, the adjuster normally used for yaw adjustment must be actuated along with the corner adjuster the exact same distance. For gimbal yaw adjustment, the adjuster normally used for pitch adjustment must be actuated along with the corner adjuster the exact same distance. In this way, the mirror is being rotated about two virtual axes that intersect at the center of the optic, aka gimbal movement. Adjust one actuator at a time and the mount acts as a standard kinematic optical mount. Adjust all three actuators to translate the optic in Z-axis.
Sapphire kinematic pads create contact surfaces for the adjustment screws that have very low friction and will not will not dent under normal use. Sapphire ensures excellent
adjustability and stability.
Another benefit of the corner mount design is the additional space between the optic and the adjustment knobs. This allows for sharper beam splitting angles and easier access to the adjustment screws.
All of Newport's Industrial mounts have Allen-key adjustments to save space and prevent unintended adjustment.
Since grease can migrate, causing long-term creep, these mounts are exclusively fitted with thread-matched adjustment screws which need almost no grease. The result is actuators that have very smooth movement, and mounts with exceptional long-term and thermal stability.
