The a|Waveλdapt is a divergence adjuster
and the perfect complement to the a|BeamExpander
if an application requires it to be used at a different wavelength than its design wavelength. This distorts the wavefront and generates a convergent or divergent output beam. The a|Waveλdapt solves this problem and provides a perfectly collimated beam. It covers the entire spectral range from 500 nm to 1600 nm
, adjusts divergences and corrects wavefront deviations while maintaining the beam diameter up to 1 mrad. For each beam expander from asphericon you can purchase a suitable divergence adapter in the four design wavelengths 532 nm, 632 nm, 780 nm and 1064 nm. Thanks to its metric fine thread the a|Waveλdapt, like all BeamTuning products, can be easily integrated into any optical system and combined with up to five additional BeamTuning elements
. By compensation of the wavefront errors, the a|Waveλdapt operates completely diffraction-limited and under the adapted magnification.
