NYFORS CleaveMeter 2

Neues, hochauflösendes Interferometer zur schnellen und komfortablen Bestimmung von Bruchwinkel und Oberflächenqualität der Faser nach dem Cleave. Die Ansteuerung und Stromversorgung erfolgt über die USB-Schnittstelle. Die Software ermöglicht es durch Mausklick den Bruchwinkel entweder über Teilbereiche oder auch über die gesamte Faser automatisch zu berechnen und am Bildschirm anzuzeigen. Zur Dokumentation kann das Bild zusammen mit dem Messwert in einer Datei gespeichert werden.

Short facts

  • Sharp fringe patterns
  • Flat and angled cleave measurements
  • Operator skill independent for fast operation
  • Documents images from critical end-faces in production and laboratory environments
  • Accepts fibers with cladding diameters from 125 µm to 1200 µm
  • Accepts fiber holders of major splicer manufacturers
  • Adaptor plate angle error measurement and compensation (premium software)
  • Plane angle and three-point fiber diameter measurement (premium software)


The CleaveMeter 2™ is a non-contact interferometer designed for inspecting the end-faces of cleaved or polished optical fibers with cladding diameters of 125 µm to 1200 µm. It gives immediate information on important end-face properties such as flatness, perpendicularity, hackles and dust. Sampling tests as well as continuous process documentation can be carried out both easily and quickly, making this an ideal instrument for cleaver inspection and optimisation.

The optical system is based on a high-end camera with true megapixel resolution and very high sensitivity, yielding excellent image quality at high frame rates and high magnification. Switching between low and high magnification is software-controlled. High-precision optics guarantees sharp and clear images and fringe patterns with very little aberration.

The CleaveMeter 2™ comes with user friendly and efficient software available in two different versions - standard and premium. Standard software features include cleave angle measurements with in-picture presentation of results, user-defined markers at points of interest, pseudo-colour mode for better constrast and the ability to log information, save and load images to and from files. The premium package includes support for measurement of plane angles and fiber diameters as well as compensation for adaptor plate angle error for increased accuracy.

Adaptor plates are available for both perpendicular and angled cleave measurements.The mechanical design is compatible with all NYFORS automatic fiber cleavers and accepts the fiber holders used with those machines as well as those of major splicer manufacturers. Customised adaptor plates are available upon request.

The CleaveMeter 2™ comes in a small ergonomic, bench-top design and connects to the USB port of a PC running the host application.
