Fascination for Innovation
SLI 202 / ALI 202

The compact workshop interferometers enable placement on the production floor, providing ready access to the optician and increased productivity.

The vertical vibration-isolated design requires minimum floor space. The full housing protects the instrument in less-than-ideal environments.

A live monitor display of the fringe patterns makes the alignment easy. The phase measuring feature results in an accurate wave front map which you can further study by the user-friendly analysis software.

Optional precision distance measurement devices allow for an accurate positioning of the lens. Also an add-on, the fully automated alignment feature uses motorized translation and rotation stages to move the lens, and for aspheresthe computer-generated hologram (CGH), to get very reproducible measurements.

The interferometer is available as SLI 202 spheric version or ALI 202 aspheric version enabling precise radius and shape measurement of virtually any precision optics.
