Alignment Autocollimator



We are the only manufacturer & suppliers of Alignment Autocollimator in india. An autocollimator is for measurement of angular tilts and an optical alignment telescope is for establishing an accurate line of sight or for measurement of linear shift . Alignment Autocollimator is a combination of Alignment Telescope and Autocollimator

Autocollimator Mode
Where a collimated light beam is projected out of the Instrument and received back after the reflection from a mirror target.

Telescope Mode
Telescope mode where the lens position is altered to focus a cross line target located at different distances. The advantage of this Instrument is to measure the angular tilts and the shift of centre location in one setting.
