VIRUS is the visible, integral-field replicable unit spectrograph for the Hobby-Eberly-Telescope (HET) consisting of 75 integral-field-units that feed 150 spectrographs. The full VIRUS instrument features over 33,000 fibres, each projecting to 1.5 arcseconds diameter on sky, deployed at the prime focus of the upgraded 10m HET. The assembly and acceptance testing for all IFUs includes microscopic surface quality inspections, astrometry of fibre positions, relative throughput measurements, focal-ratio-degradation evaluation, and system acceptance using a VIRUS reference spectrograph to verify the image quality, spectral transmission, stability, or to detect any stray light issues.
