SPIRou: the near-infrared spectropolarimeter/high-precision velocimeter for the Canada-France-Hawaii telescope

SPIRou is a near-TB. echelle spectropolarimeter and high-precision velocimeter under construction as a next-generation instrurrient for the Canada-France-Hawaii-Telescope. It is designed to cover a very wide simultaneous near-IR spectral range (0.98-2.35 mu m) at a resolving power of 73.5 K, providing unpolarized and polarized spectra of low-mass stars at a radial velocity (RV) precision of 1 m/s. The main science goals of SPIRou are the detection of habitable super-Earths around low-mass stars and the study of how critically magnetic fields impact star / planet formation. Following a successful final design review in Spring 2014, SPIRou is now under construction and is scheduled to see first light in late 2017. We present an overview of key aspects of SPIRou's optical and mechanical design.
