VIRUS-W A fiber based integral field unit spectrograph for the study of galaxy bulges

We presented the design for a fiber based integral field unit spectrograph for the new two meter class Wendelstein telescope in Bavaria, Germany. The proposed spectrograph will feature a fiberhead consisting of 246 individual optical fibers and a field of view of approximately 1' × 2' and two different spectral resolution modes optimized for the study of bulges of local late-type galaxies.
