Non-Contact Surface Profile

Interferometers are widely used for non-contact, nanometer resolution, surface profile measurements in the optics industry. Interferometers utilizing LED light sources for several hundred µm fields of view (FOV) were developed specifically for inspecting the endface geometry of fiber optic connector endfaces. This type of interferometer is also capable of taking surface profile measurements of any surface that can be imaged in the FOV. The FiBO 300 model was designed with multiple FOV options, which allow for the measurement of large diameter fibers, fiber endcaps, micro optics, etc.

Many new types of fiber with assorted structures or features inside the fibers require measurement of surface geometry as well as analysis of the fiber features. Software tools like 2D side profiles, distance measurements between features, and angular measurements between features have been incorporated into FiBO Code software for just these applications.

As electronics become smaller, corresponding optical systems are also getting smaller. The FiBO 300 takes radius and flatness measurements of micro optics, <20 µm radius, with areas of interest smaller than 1 mm.
