AUTOCOLLIMATING ALIGNMENT TELESCOPE -- D-275The Model D-275 Autocollimating Alignment Telescope can be focused from 16" to infinity to align any number of points along its optical axis. Due to the fact that the mechanical axis of the tube and the optical axis of the instrument are parallel within 3 seconds, the instrument is easily adaptable to jigs and setups using a dial indicator.
A reflective surface may be established normal to the optical axis by utilizing the autocollimating feature. The Model D-275 is designed to provide the most-needed features as standard equipment at a low price. |
