Applications

WLI (While Light Interferometry) technology combined with a piezo motor allows extremely fast measurements.
The table allows manual movement with workpieces weighing up to 5 kg.
Motorized tables are available as an option to extend the X&Y measuring range.

		Z-axis displacement The Z-axis travel wheel has two functions: quick movement and fine positioning to easily adjust the working distance.			Mounting Bases The table's thumbwheel allows precise movement in X & Y.

		Tilt Adjustment The tilt adjustment of the table is done using the two knobs on the front of the table.			Optics A carousel of optics is available as an option.
