Description
The Autocollimator is a single instrument combining the functions of a collimator and a telescope. It detects small angular displacements of a mirror by means of its own collimated light. Trioptics offers different autocollimators depending on the measurement tasks.
Autocollimator (Autocollimating Telescope)
The two reticles of an autocollimator with fixed focus setting are positioned in the focal plane of the corrected objective lens, so that the emerging beam is parallel. This usual configuration is known as infinity setting, i.e the autocollimators are focused at infinity.
Focusing Autocollimator
The reticles of a focusing Autocollimator (focusing Autocollimation telescope) can be moved out of the focal plane of the objective lens so that the autocollimator can be focused at finite distances and the beam becomes divergent (producing a virtual image) or convergent (real image).The shape of the beam -convergent or divergent-depends on the direction in which the reticles are moved.
Large Field Autocollimator
To meet customer requirements for testing optical instruments with large field of view, TRIOPTICS developed a new and unique line of autocollimators.
