Performance of a fibre-optic coupled, high-resolution spectrograph with CCD camera recording of solar H? and H? absorption spectra
Abstract
This paper explores the wavelength and spatial resolution of a stigmatic, 0.5m focal length, f/8.7 spectrograph investigating the solar Balmer H? and H? absorption lines, with the spectrograph output focused directly onto the CCD chip of a 1.2Mpixel digital camera using single fibre-optic coupling.
