Rotary Stage, Height-Adjustable, 25.4 mm Vertical Travel, M4 and M6

The M-488 Height-Adjustable Rotary Stage provides a large metric mounting platform, lockable motion, and a novel mechanical design that virtually eliminates all backlash and provides a rock-solid, wobble-free mount at any height. A scalloped adjustment ring provides non-rotating vertical travel over 25.4 mm with 0.01 mm graduations. A recessed locking screw securely fixes the mount at the desired height to prevent inadvertent adjustments. The lockable, rotating platform has a knurled rim for coarse adjustment with graduations every 2°. The mounting platform offers a generous array of mounting holes for attaching other components. In addition, prisms and beamsplitter cubes up to 50.8 mm high can be easily and securely held by the removable clamps that thread into the top of the platform.
