Cleave process

Cleaving refers to a process for preparing the end faces of glass fibers by controlled breaking.


A collimator is an optical device for parallelizing light beams, such as converging lenses or concave mirrors.

Confocal microscopy

Confocal microscopy is an optical imaging technique for generating high-resolution 3D images. Here, a laser scans multiple image planes, which are then assembled by a computer. Only the reflected light from the focal plane is detected through a pinhole. This allows very high resolutions to be achieved.

Corundum blasting

Corundum blasting is an abrasive process for surface treatment in which corundum is used as the blasting medium. This process is suitable for removing layers of rust, scale, and paint.

Cutting edge roughness

In the case of cutting tools, cutting edge roughness refers to the non-uniformity along the cutting edge. It is a measure of micro deviations between the nominal and actual geometry of the cutting edge.
