We present the mechanical design and analysis of CUBES (Cassegrain U-Band Efficient Spectrograph), a near- UV spectrograph for the ESO Very Large Telescope (VLT). First, we describe the challenges and key concepts of the mechanical design. Then we report on the finite element analysis (FEA) covering modal and seismic a...

Stable broadband Fabry–Pérot etalons are essential calibrators for extreme-precision radial-velocity (EPRV) spectrographs, providing dense, uniform reference spectra with the line symmetry and long-term stability required to achieve centimeter-per-second sensitivity. The ultimate spectral stability and uniformity of th...

In the era of Extremely Large Telescopes, the current generation of 8-10m facilities is likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Cassegrain U-Band Efficient Spectrograph (CUBES) has been designed to provide high instrumental efficiency (> 37%) for observations in the near UV...
