Binospec：用于MMT的宽视场成像光谱仪
Binospec: A Wide-field Imaging Spectrograph for the MMT
摘要：
Binospec是一款高通量的370至1000 nm成像光谱仪，可处理两个相邻的8'× 15'视场。Binospec于2017年底在650万MMT的f/5焦点上投入使用，现在可供所有MMT观察员使用。使用激光切割机从不锈钢切割的孔眼掩模用于限定范围从15“长狭缝到数百个2”狭缝的入口孔眼。系统吞吐量，包括MMT的反射镜和f/5宽场校正器，峰值约为30%。三个反射光栅，为两个光束复制，提供1300和$>$ 5000之间的分辨率（$λ$ / $Δλ$），具有1”宽的狭缝。两个穿过掩模的引导器用于目标获取、掩模对准、引导和精确偏移。全时夏克-哈特曼波前传感器允许连续调整主镜支撑力、望远镜准直和聚焦。主动挠曲控制在变化的重力和热条件下保持摄谱仪对准和聚焦。
英文摘要：
Binospec is a high throughput, 370 to 1000 nm, imaging spectrograph that addresses two adjacent 8' by 15' fields of view. Binospec was commissioned in late 2017 at the f/5 focus of the 6.5m MMT and is now available to all MMT observers. Aperture masks cut from stainless steel with a laser cutter are used to define the entrance apertures that range from 15' long slits to hundreds of 2" slitlets. System throughputs, including the MMT's mirrors and the f/5 wide-field corrector peak at ~30%. Three reflection gratings, duplicated for the two beams, provide resolutions ($λ$/$Δλ$) between 1300 and $>$5000 with a 1" wide slit. Two through-the-mask guiders are used for target acquisition, mask alignment, guiding, and precision offsets. A full-time Shack-Hartmann wave front sensor allows continuous adjustment of primary mirror support forces, telescope collimation and focus. Active flexure control maintains spectrograph alignment and focus under varying gravity and thermal conditions.
