Edmund Optics' TechSpec goniometers enable precise angular adjustment of an object about a fixed point located above the center of the mounting surface.

They provide accurate, true tip-and-tilt adjustment of any optical component and are commonly used to accurately direct lasers and precisely align mirrors in beam steering applications. Mechanically compatible with the company’s other TechSpec stages, they are available with metric and English hole patterns for a wide variety of uses.

The goniometers are available in plate sizes to accommodate a wide range of applications. Each size – 30, 40, 70 and 125 mm – is offered in several radii of movement for easy stacking into two-axis rotation configurations. To provide motion about a common point in two axes, the user should mount the goniometers with smaller radii on top of those with larger radii of the same stage size.

The devices feature precision movement along a dovetail design with a vernier scale for accurate, high-resolution measurements and good movement repeatability. A locking thumbscrew allows each setting to be held securely in place. The 30- and 40-mm instruments are manufactured of durable black-painted brass, while the 70-mm models are constructed of sturdy black-anodized aluminum. The 30- and 40-mm stages require bottom adapter plates to mount to standard breadboards. The 70- and 125-mm stages mount directly to standard breadboards.

The components are easily integrated into complex assemblies through the available IGES and STEP files.
