Manual Stages

Optosigma Manual Stages are precision mechanical positioning devices operated by hand-adjusted micrometers or lead screws, providing controlled translation or rotation of optical components and samples without motor drives. They are the standard for optical bench setups and microscopy sample positioning.

Manual linear stages:
– Travel range: 5 mm (compact) to 150 mm (long travel) depending on model
– Actuators: micrometer head (0.01 mm graduation), differential micrometer (0.001 mm graduation), or lead screw with graduated thumbwheel
– Crossed roller bearing guides: smooth, low-friction travel with minimal lateral run-out
– Load capacity: 1 kg to 30 kg depending on stage size
– XY combinations: two crossed linear stages for two-axis translation

Manual rotation stages:
– 360 degrees continuous rotation with locking clamp
– Worm gear drive: fine angular adjustment with coarse rotation; resolution down to 1 arcmin with vernier scale
– Used for: polarizer and wave plate orientation, sample rotation, fiber angle alignment

Goniometer stages:
– Tip-tilt (goniometer) stages: for angular tilting of samples or optics; travel typically plus/minus 10 to 30 degrees
– Used in diffraction, X-ray crystallography, and surface angle adjustment

NewRoad provides Optosigma manual stages in Israel for optical alignment, laser setup, microscopy, and sample positioning in research and industrial labs.
