Abstract

The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) is an Integral Field Spectrograph (IFS), under construction for W. M. Keck Observatory. It is optimized for 2 to 5-micron spectroscopy of exoplanets and also has a 1 to 5-micron imaging channel. As various optics arrive, we aim to validate their performances individually. In this paper, we present measurements and measurement techniques used to validate SCALES optics in the lab, including filter substrates, pupil masks for the cold stop and Lyot stops, neutral density filters, and diamond-turned mirrors.
