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 introduced by changing the wavelength away from the design wavelength is achieved by employing a new add‐on element, which enables the use of monolithic beam expanders from 500 nm to 1600 nm.
