Abstract We report on the design, manufacturing, and performance of the image slicer for the High Dispersion Spectrograph on Subaru Telescope. This instrument is a Bowen–Walraven type image slicer, providing five images of 0. ”3 × 1. ”5 with a resolving power of R=λ/δ λ= 110000. The resulting resolving power and line profiles have been investigated in detail, including estimates of the defocusing effect on the resolving power. The throughput in a wavelength range of from 400 to 700 nm is higher than 80%, thereby improving the efficiency of the spectrograph under a seeing condition of 0. ”7 by a factor of 1.8.
