Lens testing


The Kaleo-MultiWAVE bench is an advantageous alternative to the purchase of several interferometers, this bench offers a measurement accuracy that rivals to interferometry. With the Kaleo-MultiWave bench you can work at different wavelength to fit the coating transmittance (TWE) and reflectance (RWE).


UNIQUE INTERFEROMETER | Wavefront error at several wavelengths

The Kaleo-MultiWAVE bench is a unique instrument that delivers wavefront error at multiple wavelengths. Optics such as lenses, filters or mirrors can be characterized at their working wavelength. Moreover optics having a coating can be measured without selective absorption issues.

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.
