Kaleo MultiWAVE

Introduction

UNIQUE INTERFEROMETER | Wavefront error at several wavelengths


The KaleoWave 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.
