The CLEAVEMETER 2 and 3D has gained a new optional operation mode for inspecting the fiber without interference fringes. While the interference is essential to compute an accurate cleave angle of a fiber end-face, a simple microscopic inspection of the fiber is useful for finding impurities or overall damages on the fiber.

For this the CLEAVEMETER 2 and 3D can now be equipped with a simple add-on that allows for direct visual inspection of the fiber end face. The tool is meant to be used in conjunction with the interferometric feature of the device and as such the device can be switched between the two operation modes in a few seconds. This new feature can be especially useful for structured fiber, in order to visually establish first that the structure has not been damaged before evaluating a cleave angle.
