상품 상세설명

NP250-2M Spectrograph ?


NP250-2M is a spectrograph with two independent spectral channels.


Focal length of each channel is 250 mm. F/number of the device is 1/4.2, F/number of each channel is 1/6.1.


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.
