The Phasics KaleoMultiWAVE bench is a unique instrument that delivers wave front error at multiple wavelengths. Optics such as lenses, filters or mirrors can be characterised at their working wavelength. The KaleoMultiWAVE works at different wavelengths to perform qualification of the optics and coating at the working wavelengths of the coating.

The KaleoMultiWAVE bench is an advantageous alternative to the purchase of several interferometers, the system offers a measurement accuracy comparable to interferometry.

The bench offers a superior accuracy similar to interferometry and a very great dynamics over large diameter.

Measurement are done in double pass, either in transmission or reflection.
