The VIRUS2 Instrument is the next generation replicated integral field spectrograph
for the 2.7m Harlan J. Smith Telescope at the McDonald Observatory. The instrument
extends the technological advances from VIRUS and HET LRS-2 instruments to offer higher
spectral resolution of R>2000 over a broader wavelength coverage from 370nm to 1000nm
and a larger sky area of 2 arcmin diameter in a single shot with spatial sampling
of 2.6 arcsec. The instrument also utilizes fiber integral field units (IFUs) coupled
with micro-focal reducers to offer nearly 100% fill-factor on sky. VIRUS2 is the successor
of the Mitchell Spectrograph (aka. VIRUS-P) on the HJST. There is also a potential
for its scientific use on the Giant Magellan Telescope as an early phase instrument.
