High-resolution spectrograph for telescopes of moderate diameter

A base model of the high-resolution fiber-fed spectrograph is developed. In combination with the SAO 1-meter telescope the spectrograph has the following parameters: spectral resolution R=45000, the number of simultaneous registered orders is 86 within spectral region 3850$÷$10850 \AA{}, echelle orders are overlapping for $\lambda <9000$ \AA{}.
