Thorlabs 3-Axis RollerBlock stage

Thorlabs' Rollerblock long-travel stage with 148-801ST micrometers provides 13 mm (1/2") of coarse travel. The coarse adjuster has a Vernier scale with 10 µm graduations for a resolution of 5 µm. This resolution and long-travel range make these stages ideal for optimizing the coupling efficiency in a fiber alignment or waveguide positioning system. The graduations also allow for a clear reference point for absolute positioning within a system.
