VIRUS2仪器是麦克唐纳天文台2.7米Harlan J. Smith望远镜的下一代复制积分场光谱仪。该仪器延续了VIRUS和HET LRS-2仪器的技术进步，在370nm至1000nm的更宽波长覆盖范围内提供R<2000的更高光谱分辨率，在2.6弧秒的空间采样中，单次拍摄的天空面积更大，直径为2弧分。该仪器还利用光纤积分场单元（ifu）与微焦减速器相结合，提供接近100%的天空填充系数。VIRUS2是米切尔摄谱仪(又名。病毒p)在HJST上。它也有可能在巨型麦哲伦望远镜上作为早期仪器进行科学应用。
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. T ere is also a potential for its scientific use on the Giant Magellan Telescope as an early phase instrument.
