Large Diameter Mirror Mounts

Newport offers over 25 large diameter mirror mounts for 3.0 in. (76.2 mm), 4.0 in. (101.6 mm), 6.0 in. (152.4 mm), and 8.0 in. (203.2 mm) diameter mirrors.

Kinematic mounts are the most popular and least expensive. A disadvantage with a kinematic mount is that the mirror center moves along the normal axis when tip/tilt adjustments are made. Gimbal Mounts are more expensive, but are able to solve the problem of unwanted normal motion.

Our large diameter mirror mounts come equipped with three types of drives. Allen-Key versions are adjusted using an allen wrench. Knob versions can be adjusted by hand. Micrometer versions can be adjusted by hand and provide a scale to measure the adjustment. We also offer adjustment knobs that can be used to adjust Allen-Key versions by hand.
