About FDRF651 Optical Micrometer

Direct thru-beam micrometer, long distance between receiver/transmitter

Optical Micrometers: Laser/LED based for diameter, edge and gap measurement
Optical Micrometers are devices providing non-contact measurement of diameter of wires, rods and cylinders as well as gaps, edge positions and other dimensional characteristics of geometric objects. Althen offers both laser and LED based optical micrometers.

These micrometers determine with high precision the dimension and position of an object by using the "shadow" measurement principle. Collimated laser light (the rays are parallel) is transmitted by the system lens arrangement towards a receiver. The edges of the shadow in the beam’s curtain are accurately measured in the receiver’s detector array.
