Optical Micrometers 1D RF651 - RF656 Series
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.

Model RF651 Operation Principles
The micrometer operation is based on the so-called ‘shadow’ principle. The micrometer consists of two blocks — transmitter, 1 and receiver, 2. Radiation of a LED 3 is collimated by a lens 4. With an object, 5 placed in the collimated beam region, shadow image formed is scanned with a CCD photo-detector array 6. A processor 7 calculates the position (size) of the object from the position of shadow border (s).
Model RF656 Operation Principles
The micrometer operation is based on the so-called ‘shadow’ principle. The micrometer consists of two blocks — transmitter, 1 and receiver, 2. Radiation of a red LED 3 is collimated by a lens 4. With an object, 5 placed in the collimated beam region, shadow image formed by telecentric lens 6 and is scanned with a CCD photo-detector array 7. A processor 8 calculates the position (size) of the object from the position of shadow border (s).
