NP250-2 is a completely automated spectrograph with two independent spectral channels. Focal length of each channel is 250 mm. F/number of the device is 1/3.8, F/number of each channel is 1/5.3. The radiation, after passing the entrance slit, is split into two independent spectral channels, representing a separate automated spectrograph, designed on the modified Hill scheme. Such an optical scheme allows to avoid spectra re-entrance from the diffraction gratings and mirrors, the parabolic mirrors allow to obtain high spatial and spectral resolution.
