In-situ analysis include the following major advantages:

Laser machining – also known as Laser Micro Milling – is a generic machining process which involves the removal of material to a specified depth, creating a variety of relief features such as grooves, slots and profiles, without actually cutting through the material. This technique is used frequently in the medical and electronics industries.

Laser micro milling is applied to create features in flat or contoured surfaces. Beam scanning, mask imaging, or a combination of the two provides great flexibility in the range of features that may be produced. With precise control of the processing depth, OpTeks' laser milling can be applied in layers to create deeper features.
