tilting in two dimensions
attocube’s goniometers are much more compact than tripod setups starting from just over 15x15x20 mm3 of space.
Each size of goniometer is available in two versions which are usually used as a pair for theta (Θ) and phi (Φ) motion. The theta positioner mounted on top of the phi positioner they form a tip-tilt stage with a common center of rotation (see sketches below). Mounting is directly done via two or four screws.
There are three different pairs of goniometers available: ANGp/t50, ANGp/t101 and ECGp/t5050. The latter two can also be equipped with integrated encoders. Combinations with other positioners are explained on the page to the left respectively in the accessories sections of the Premium and Industrial Line.
