We present the current development of a Scanning Reflection X-ray Microscope (SRXM) based on zone plate focusing in the extreme ultraviolet (EUV) spectral range at the DELTA beamline 12. The SRXM is dedicated to magnetic domain imaging in magnetic films, surface of thick samples and buried layers exploiting magneto-optical reflection spectroscopy employing T-MOKE, L-MOKE, XMLD and XMCD [1]. We present the construction of the microscope and discuss the fabrication of zone plates using absorbing gold structures as well as phase shifting PMMA structures. Both variants are designed for EUV applications across the Fe 3p to Ni 3p edges and are deposited on Si3N4 membranes. Ray tracing calculations for the beamline including zone plate optics are presented as well. [1] M. Tesch, M. Gilbert, H - Ch. Mertins, D. Bürgler et al., Appl. Opt. 52, 4294 (2013)
