autocollimator

[¦ȯd·ō′käl·ə‚mād·ər]
(optics)
A device by which a single lens collimates diverging light from a slit, and then focuses the light on an exit slit after it has passed through a prism to a mirror and been reflected back through the prism.
A telescope which has a graduated reticle, enabling an observer to read off the angles subtended by distant objects.
A convex mirror at the focus of the principal mirror of a reflecting telescope, which causes light to leave the telescope in a parallel beam.
A telescope equipped with an eyepiece designed for autocollimation.
