Interferometer developed for Newtonian fringe inspection of mass-produced products.

If the jig on which the subject is placed is fabricated in advance, the Newtonian fringes can be tested simply by first adjusting the jig with a reference standard and then changing the subject.

A wide measurement range is covered by a rich lineup of 8 types of reference lenses.

Two types of spherical stands are available: a standard type (120 mm) and a long axis type (360 mm), which can be selected according to the stroke required for the measurement of the specimen.

Flat surface measurement is also possible by attaching a reference plate for flat surface measurement.
