The CLEAVEMETER 3D+™ is a non-contact interferometer designed for high accuracy inspecting of end-faces for cleaved or polished optical fibers with cladding diameters of 125 μm to 1200 μm. The CLEAVEMETER 3D+™ gives immediate and precise information on the important end face properties such as flatness, perpendicularity, hackles and dust. Extremely accurate measurements of both cleave angle and surface flatness over arbitrary diameters can be performed on the reconstructed end-face surface. These measurements are carried out automatically, with full operator independence.

This makes the system well suited not only for detailed cleave quality analysis in laboratory environments, but also for close production monitoring. In addition to cleave angles, the system can also be used to measure a number of other properties such as plane angles, fiber diameters and the distance between points.

The software allows the user to view the pointwise slope across the whole fiber end-face, a very useful tool for spotting small scale irregularities and crack propagation behaviour. The CLEAVEMETER 3D+™ comes in a small, ergonomic benchtop design and connects to the USB port of a PC running the host application.
