KIF-10A-NW/NTW is a KIF-10A-applied measuring device for Newton evaluation. It allows easy and quick inspection by comparing the number of Newton rings with that on a Newton standard plate.

Stabilized inspection/measurement
The compact desktop design of this device saves installation space. In addition, it takes little time to mount and dismount a test lens since measurement is made by just placing the lens from above. Equipment with an anti-vibration structure enables easy, stable inspection and measurement.
Easily-variable measurement posture (KIF-10A-NW)
Since a measurement posture can be changed by merely changing the mounting positions of the legs, the device can be used as an upward type or downward type according to a test piece.
Smooth introduction to existing inline processes through the use of 635nm laser wavelength
Since the laser wavelength is close to that of the conventional Fizeau interferometer (632.8nm), equivalent interference fringe sensitivity can be obtained. This allows smooth introduction of this model to an existing inline inspection process.
Olympus' rich reference lens lineup
One-inch and compact-type specifications are used for reference lenses, with a wide choice of options similar to the KIF-202L series.
