Product Family Description

  • Stackable for Two-Axis Rotation
  • Durable Brass Construction
  • Dovetail Design with Vernier Scale

Metric Goniometers allow for precise angular adjustment of an object about a fixed point located above the center of the mounting surface. Stages with smaller radii can be mounted on top of larger radii stages of the same size to provide motion about a common point in two different axes. All stages feature a precision dovetail movement with a Vernier scale for high-resolution measurements and movement repeatability. Metric Goniometers feature a locking thumbscrew, allowing each stage to be held securely in place. Stage material is a durable black painted brass. An available 40mm square, 8mm thick top mounting adapter plate #58-290 mounts to M3 holes and provides a counterbore for ¼-20 or M6 socket head cap screw.

40mm Square Metric Goniometers are compatible with the following stages: #55-029, #55-030, #55-031, #55-838, and #55-839.

60mm Square Metric Goniometers are compatible with the following stages: #54-687, #55-032, #55-459, #55-527, #56-335, and #56-336.
