We present technical demands for such an instrument and its brief description. This device denoted as linage Selector is a post-focus instrument installed at the horizontal solar telescope HSFA2 of the Ondrejov observatory, described by Kotrc (2009). Its core consists of a system of diaphragms, imaging Ha telescope and a fast spectrometer with dispersion of 3 px per angstrom but with cadency reaching up to 50 frames per second. The first solar flares observed recently by this novel technique provide quite interesting results. Our analysis of the data proves that the described device is sufficiently sensitive to detect variations in the Balmer continuum during solar flares.
