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.
