Abstract

In this paper we describe the recent advances in the development of new technologies applied in the construction of Integral Field Units (IFUs) at Laboratório Nacional de Astrofísica (LNA). Our prototype is the Eucalyptus lenslet IFU constructed for the 1.6m telescope at Pico dos Dias Observatory (OPD), Brazil. This first concept was the basis to build two other IFUs with significantly improved concepts: the SOAR Integral Field Unit Spectrograph (SIFS) and FRODOSPEC. All the new technologies used in the construction of these IFUs are described in detail in this paper and can be replicated in similar instruments with optical fibers, with considerable advantages over the traditional technologies.
