Large measurement range for the smallest structures

White-light interferometer tests flexible hybrid electronics

Flexible strain gage sensor for respiration monitoring

When testing the surfaces of the finest structures, white-light interferometers are in their element, both in electronics manufacturing and development, as well as in laboratories and research. The process is non-contact and works on almost all materials. In this respect, three-dimensional optical metrology not only provides a functional and structural analysis as a basis for quality control and production optimization, but also an image of the surface that is easy for humans to understand. This benefits all areas of electronics manufacturing, including current projects in the field of flexible electronics.
