Optical micrometers use a “shadow” measurement principle whereby collimated laser light is transmitted towards a receiver. The edges of the shadow cast by an object in the beam’s path are accurately measured by the detector array inside the receiver unit. Optical Micrometers are non-contact devices that ideally measure diameters of wires, rods and other cylinders in addition to gaps, edge positions and dimensional characteristics of geometric objects.
The series includes two lines of models:
RF651 — direct through beam micrometers;
RF656 — high precision through beam micrometers with telecentric lens;
RF656XY — high precision two-axis micrometers.
