The Cosmological Advanced Survey Telescope for Optical and ultraviolet Research (CASTOR) is a proposed wide-field (30’  x 30'), high-resolution (FWHM ~0.15''), 1-m space telescope mission in development at the National Research Council of Canada and the Canadian Space Agency. Optimized for UV/blue-optical wavelengths (150 to 550 nm), CASTOR’s wide- and deep-field surveys will enable discoveries ranging from galaxy evolution and AGNs to stellar astrophysics.

The Ultraviolet Multi-Object Spectrograph (UVMOS) is a proposed instrument for CASTOR that will enable low-medium resolution (R~ 1400) spectroscopy. UVMOS demonstrates a new technique for multi-object spectroscopy using Digital Micromirror Devices (DMD). This talk will provide a general overview of CASTOR's science missions and instrument design, followed by a focus on the ongoing UVMOS instrumentation work conducted at the University of Manitoba and our collaborating institutions.
