DOI: 10.1088/1538-3873/abc7ee
Abstract: We present the design and testing of a prototype in-plane echelle spectrograph based on an actively controlled fiber-fed double-pass design. This system aims to be small and efficient with the minimum number of optical surfaces—currently… read more here.

DOI: 10.1364/ao.56.004284
Abstract: In the present article we consider an accurate modeling of a spectrograph with a cascade of volume-phase holographic gratings. The proposed optical scheme allows us to detect spectra in an extended wavelength range without gaps,… read more here.
