Description
The CleaveMeter 2™ is a non-contact interferometer designed for inspecting the end-faces of cleaved, lensed 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 optimization.
By means of the host application the operator can view the live camera image, adjust camera settings, save and load images to and from file, and log all information in a specific text-based log file. Software-compensation for fiber holder error allows for high-precision measurements with in-picture presentation of the cleave angle. This enables operator skill independence and easy process verification in production environments. Other useful software features include user-defined markers at points of interest, three-point fiber diameter measurement and pseudo-color mode for better contrast.
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 pictures with very little aberration.
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. Customized 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.

Selection Guide
Fiber-specific adaptor plates are required in order to properly align different fiber sizes to the center of the CleaveMeter™ optical system field of view. They are not included in delivery and should be ordered separately.
Adaptor plates are available for use with NYFORS automatic fiber cleavers and fiber holders of major splicer manufacturers such as Ericsson, Fujikura/AFL and Furukawa/FITEL. Below you find a selection of the most common types and dimensions. NYFORS generic adaptor plates are compatible with NYFORS LD fiber clamps and Ericsson FSU-clamps.
Please select adaptor plate to match fiber cladding diameter and angle adaptor plate (optional) to match fiber tilt angle.
