HARMONI是一种可见光和近红外（0.5至2.45 μm）积分场摄谱仪，提供E-ELT的核心光谱能力，分辨率范围为R（λ/Δλ）~ 3500至~18000。该仪器同时提供了1032000个排列在平方（2）：1纵横比连续字段中的spaxels的光谱。前置光学系统将光（从望远镜或校准系统）引入科学低温恒温器，重新格式化和调节，以适合仪器其余部分的输入。这涉及到许多功能，主要是通过一组可互换的比例变化光学器件将光从望远镜焦平面中继到积分场单元（IFU）焦平面。前置光学系统还提供包括焦平面掩模轮、冷光瞳掩模、光谱阶数排序滤波器、快速快门和光瞳成像能力的组件，以检查望远镜/仪器光瞳对准。在本文中，我们介绍了初步设计评审中HARMONI前置光学器件的光学设计，特别是，我们详细介绍了与先前设计的差异以及初步设计评审中遇到的困难。
HARMONI is a visible and near-infrared (0.5 to 2.45 μm) integral field spectrograph, providing the E-ELT's core spectroscopic capability, over a range of resolving powers from R (λ/Δλ) ~ 3500 to ~18000. The instrument provides simultaneous spectra of ∼32000 spaxels arranged in a sqrt(2):1 aspect ratio contiguous field. The pre-optics take light entering the science cryostat (from the telescope or calibration system), reformatting and conditioning to be suitable for input for the rest of the instrument. This involves many functions, mainly relaying the light from the telescope focal plane to the integral field unit (IFU) focal plane via a set of interchangeable scale changing optics. The pre-optics also provides components including a focal plane mask wheel, cold pupil masks, spectral order sorting filters, a fast shutter, and a pupil imaging capability to check telescope/instrument pupil alignment. In this paper, we present the optical design of the HARMONI pre-optics at Preliminary Design Review and, in particular, we detail the differences with the previous design and the difficulties salved to the Preliminary Design Review.
