Stitching MetroPro Application

The MetroPro Stitching Application is designed to measure and analyze surface areas much larger than possible with a single measurement. Stitching makes several measurements of the test part as it is moved by a motorized stage and then combines or stitches the multiple data sets into one. Effectively, it increases the field of view without compromising lateral or vertical resolution. The graphics and results displayed on screen are based on the entire measured area.

After you define the test area, a stage pattern is created that breaks the larger area into a number of smaller sub-regions. Each sub-region is equal to the field of view of the microscope’s objective and zoom setting, minus a small percentage for overlap. After software parameters are entered the process is automatic.

A number of factors determine the maximum size of the stitched area. These include: the objective magnification, the zoom setting (microscopes with Image Zoom option only), the camera resolution (determined by the Camera Mode control), and the amount of computer RAM.

The Stitching Application supports Zygo’s microscopes, including the NewView and Maxim, as long as they are equipped with programmable motorized stages. A motorized z-drive (focus) is optional; however, it is required for extended scans or the auto focus option. The stitching application is licensed as part of standard MetroPro.
