我们提出了初步的实验室低温测试结果的日冕幻灯片机制，它允许观察者选择多达4个日冕焦平面掩模时，使用规模（圣克鲁斯阵列的小透镜的系外行星光谱）。SCALES是一台2-5微米高对比度小透镜积分场摄谱仪，目前正在为W。M.凯克天文台。当部署在凯克自适应光学系统后面时，SCALES将用于探测和表征各种系外行星。为了最大限度地减少热辐射，SCALES的所有光学和机械组件都是完全低温的。Coronagglass Slide是第一个完全用于SCALES的低温机制，主要由UCSC内部设计，制造和测试，其中大部分是现成的组件。
We present preliminary laboratory cryogenic test results for the Coronagraph Slide mechanism, which allows observers the choice of up to 4 coronagraphic focal plane masks when using SCALES (Santa Cruz Array of Lenslets for Exoplanet Spectroscopy). SCALES is a 2-5 micron high-contrast lenslet integral field spectrograph currently undergoing preliminary design for the W. M. Keck Observatory. When deployed behind the Keck Adaptive Optics system, SCALES will be used to detect and characterize a wide variety of exoplanets. To minimize thermal emission, all optical and mechanical components of SCALES are fully cryogenic. The Coronagraph Slide is the first fully cryogenic mechanism for SCALES designed, built, and tested in-house at UCSC with mostly off-the-shelf components.
