Abstract

WSO-UV is the coming mission for ultraviolet astronomy. The telescope is equipped with instrumentation for imaging and spectroscopy in the 115 nm-315 nm spectral range. The far ultraviolet imager on board WSO-UV will obtain 100 mas angular resolution images from geosynchronous orbit in five far UV bands within the 115 nm-175 nm spectral range. Additionally, it will be equipped with prisms to obtain slit-less spectroscopy with dispersion 500 around the relevant spectral lines (Lyman-a, CII at 134 nm and CIV at 155 nm). A laboratory for vacuum ultraviolet optics has been developed in the premises of the Universidad Complutense de Madrid to test the optical performance of the channel. An optical emulator of the WSO-UV beam has been developed to fit within the modular vacuum chamber. An MCP detector with an optical architecture similar to the flight detector has been produced specifically for the tests. In this presentation, we describe the laboratory set-up and the optical emulator developed for the tests.
