New stellar spectrometer on the CCD-line.
Abstract
A spectrometer for measuring the energy distribution in stellar spectra in the wavelength range from 0.4 to 1.0 micron is presented. Spectra are registered by means of a linear CCD array. The optical scheme with cross dispersion is applied in the spectrometer, which makes it possible to observe a stellar spectrum in two orders of grating: the first order has a wavelength range from 0.63 to 1.0 micron, and the second one, from 0.4 to 0.67 micron.
