The workshop interferometers SLI 101/201 can be equipped with different interferometer modules of the 4" and 6" sizes. There are low-cost modules available for a visual evaluation of form errors as well as models with phase modulator and software supported evaluation.

SLI workshop interferometers make it possible to measure radii and analyse form errors of spherical surfaces in optical production. Due to the combination of modern metrology and ergonomic workshop suitable design, a maximum of precision and ease of operation will be guaranteed.
