The 77477 MS127i Ruled Grating is supported on a precision holder, which clips into the grating mount of a MS127i 1/8 m Imaging Spectrograph. This grating has a 400 l/mm line density and has a peak efficiency of 85% at the 1600 nm Blaze Wavelength. It's efficiency exceeds 20% over the 900 to 2900 nm primary wavelength region. 3600 nm is the MS127i upper wavelength mechanical limit for this grating. These gratings are individually replaceable in the field, and can be easily interchanged without the need to realign the instrument.
