For several testing applications, non-contact measuring extensometers provide significant benefits over traditional, contact-type extensometers. One of their main features is in the name itself, as ...

Optical non-contact profilers are interference microscopes used to accurately measure the three-dimensional height variations on surfaces of a given test material. Optical profilers manipulate the ...

OptiSurf® is the ideal tool for non-contact center thickness and air gap measurement within single lenses, planar optics and optical systems. The instrument is based on low coherent interferometry and ...

The devices in which sighting of an object is done or dimensions of an object are determined by using optical principle for the operation are known as optical measuring instruments. On the basis of ...
