Abstract

We present unique optomechanical designs allowing precise fabrication and alignment of diamond-turned aluminum image slicers through preformed monolithic blocks and, most importantly, sub-group assemblies. This last approach reduces manufacturing time and risks while resulting in more alignment flexibility when compared to the traditional monolithic slicer build. We describe all optomechanical parts included in the process, as well as the selection of tooling and machining parameters to obtain good surface quality results on the first groups of slices for the GIRMOS (Gemini InfraRed Multi-Object Spectrograph) instrument image slicer.
