论文摘要
39米的欧洲极大望远镜（E-ELT）预计在可见光光谱的蓝色部分的吞吐量非常低。因此，在8米的非常大的望远镜处的蓝色优化光谱仪有可能在短波长中与400 nm的波长竞争。该仪器的概念研究于2012年结束。这将是一项高通量，中等分辨率（r $ \ sim $ 20 \，000），在300至400 nm之间运行。目前预计该乐器的建设将在未来几年内开始。在这项贡献中，我介绍了仪器概念以及一些激励这种光谱仪的可能的银河系和外层次科学案例。
The 39-meter European Extremely Large Telescope (E-ELT) is expected to have very low throughput in the blue part of the visible spectrum. Because of that, a blue-optimised spectrograph at the 8-meter Very Large Telescope could potentially be competitive against the E-ELT at wavelengths shorter than 400 nm. A concept study for such an instrument was concluded in 2012. This would be a high-throughput, medium resolution (R $\sim$ 20\,000) spectrograph, operating between 300 and 400 nm. It is currently expected that construction of this instrument will start in the next few years. In this contribution, I present a summary of the instrument concept and of some of the possible Galactic and extragalactic science cases that motivate such a spectrograph.
