Goniometers

Goniometers are used for high resolution angle measurements of surfaces with angular differences in excess of the range of an autocollimator. A precision rotary stage and encoder is combined with an electronic or visual autocollimator to make measurements through 360°.

GONIOMAT-A-Hinter

GONIOMAT A / A-HR

The GONIOMAT A uses the same measuring principle and software as the GONIOMAT M, with increased accuracy and an automatic rotary stage. A housing around the instrument provides an environment free of external disturbances to further increase accuracy and repeatability. The GONIOMAT A is also available in two levels of accuracy:
GONIOMAT A: 0.7 arcsec
GONIOMAT A-HR: 0.4 arcsec
