The 77750 Grating Assembly is for use with the Oriel MS257 monochromator and imaging spectrograph. This grating is installed by Newport onto either the 77706 Single Grating Mount or 77708 Multiple Grating Mount that can hold up to four gratings (ordered separately). The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency of greater than 85% at its blaze wavelength.
