Abstract

We present the conceptual design of a room-temperature configurable slit unit (CSU) for the Low-Resolution Imaging Spectrograph 2 (LRIS-2), an upgraded version of a widely used instrument at WMKO. The CSU is a significant enhancement, allowing real-time reconfiguration of slit masks without the need for single-use, machined metal masks. It consists of 72 pairs of motorized bars that can align to form slits, providing flexibility for astronomers in creating various slit shapes and sizes. The CSU will be especially beneficial if Keck receives an adaptive optics upgrade as slits can be adjusted in real time to match the improved seeing.
