Research Abstract

We have developed a germanium immersion grating mid-infrared cryogenic spectrograph (GIGMICS) designed for the Nasmyth focus stage of NAOJ Subaru 8.2 m telescope, which operates at N-band (8-13 μm) in wavelength with the R～50,000. A single crystal germanium immersion echelle grating (30×30×72 mm) for collimated beam size of φ28 mm was fabricated by utilizing ultra precision micro-grinding method coupled with the ELID (ELectrolytic In-process Dressing) technique. The instrument has been assembled and is now tested for the application to the gas-phase IR high-resolution spectroscopy.
