Abstract

We present the preliminary design for the configurable slit unit (CSU) for TMT’s Wide Field Optical Spectrometer (WFOS). The design consists of 96 bar pairs that can create an arbitrary pattern of focal plane slits. The large number of motorized mechanisms to drive the bars into position requires a high reliance on off the shelf components to reduce cost and design effort. A prototype was completed that shows the selected components will likely meet requirements. The current design nearing completion as WFOS ramps into a preliminary design review in 2025.
