Optical Micrometers

RF65x_smOptical 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 and RF656 – high precision through beam micrometers with telecentric lens

  • Operation

    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 semiconductor laser 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).
