These optical pens are used for non-contact measurement, and are associated to the CHR controllers, in order to form an optical sensor.

STIL proposes two families of optical pens :

• The OP series Measuring range from 20 µm to 24 mm.

• The CL series : Modular. The modular optical design consists of the combination of a magnifier (achromatic collimator) and a chromatic lens. Measuring range from 100 µm to 24 mm.

• All these pens are entirely passive and interchangeable on a same controller.
