TriAngle, an electronic autocollimator from Trioptics GmbH, measures angles along three axes. The device features a variable measuring range and an integrated high-resolution CCD sensor. It is compatible with objective tubes of varying focal lengths and can measure optics and align mechanics. Depending on an instrument's focal length, accuracy varies from 0.2 to 2 arc sec, and resolution, from 0.01 to 0.1 arc sec. Applications include prism and polygon angles, tilt and wedge angles, and alignment of mechanical setups. Custom measuring procedures can be interfaced with the software that is included.
