Edmund Optics has introduced a range of goniometers in its Techspec product line, allowing precise angular adjustment of an object about a fixed point located above the centre of the mounting surface. The goniometers provide highly accurate, true tip and tilt adjustments of any optical component. They are commonly used to accurately direct lasers and precisely align mirrors in beam steering applications. Mechanically compatible with the company's other Techspec Stages, the new goniometer is available with both metric and imperial hole patterns for the widest variety of uses.
Different plate sizes are available to accommodate a wide range of applications. Each of the sizes, 30, 40 or 70mm, is offered in several radii of movement for easily stacking into two-axis configurations. In order to provide motion about a common point in two different axes, the user should mount goniometers with smaller radii on top of those with larger radii of the same stage size. The goniometers feature precision movement along a dovetail design with a vernier scale for accurate, high-resolution measurements and excellent movement repeatability. A convenient locking thumbscrew allows each setting to be held securely in place.
