Paper Abstract

Monolithic beam expansion elements, which can be used as a cascade and achieve construction lengths much smaller than those of conventional systems are presented. Furthermore, this system is diffraction-limited, and offers a high level of flexibility and continuous extensibility using new elements. The compensation for wavefront errors and divergence introduce by changing the wavelength away from the design wavelength is achieved by employing an add-on element, the SPA Waveλdapt, which enables the use of monolithic beam expanders from 500nm to 1600nm. We will present experimental results on the diffraction limited performance for some typical combinations out of the 230 possible setups. Furthermore, another module – a zoom lens - is introduced. Adding this element overcomes the discreet incrementation of the monolithic elements and allows for continuous enlargement from 1x to 32x.
