Laser interferometer KIF-20-DW is an interferometer system most suitable for quick quality inspection and numeric control of profile irregularities on flat and spherical surfaces at the production site.

Standard equipment with the PC where interference fringe digitization software KIF-FIA has been installed
This system allows digitized display of aberrations from interference fringes in addition to the conventional interference fringe observation.
The ability to also save and print numerical data and screen data makes it optimal for quality control in manufacturing processes.
Adoption of a new reference lens mount
The adoption of a new type dovetail-grooved reference lens mount prevents the reference lens from dropping during its mounting/dismounting and enables easy and quick replacement of the lens, thus contributing to increase in production efficiency.
Stabilized inspection/measurement
The compact, high-rigidity and vibration-protected interferometer body is excellent at environmental resistance and operability in view of the operating environments at the production site.
