  We present our progress on the UV-VIS arm of Son Of X-Shooter (SOXS), a new
spectrograph for the NTT. Our design splits the spectral band into four
sub-bands that are imaged onto a single detector. Each band uses an optimized
high efficiency grating that operates in 1st order (m=1). In our previous paper
we presented the concept and preliminary design. SOXS passed a Final Design
Review in July 2018 and is well into the construction phase. Here we present
the final design, performances of key manufactured elements, and the progress
in the assembly. Based on the as-built elements, the expected throughput of the
visual arm will be >55%. This paper is accompanied by a series of contributions
describing the progress made on the SOXS instrument.
