Paper Abstract

The Gemini High-resolution Optical SpecTrograph (GHOST) is fed by an optical cable linking the telescope and environmentally stabilized spectrograph room. Telescope input is injected into integral field units that are translated along the focal surface by positioners. Each integral field unit serves as an image slicer partitioning the seeing limited image with the help of a hexagonal microlens array. An additional microlens array is used to inject light telecentrically into each fiber which maximizes the efficiency of the cable. Spectral measurements of the optical cable throughput are presented for the design wavelength range.
