The 77410 MS125 Holographic Grating is supported on a precision holder for use with the MS125 1/8 m Spectrograph. This grating has a 1200 l/mm line density and has a peak efficiency of 80% at the 250 nm Blaze Wavelength. It's efficiency exceeds 20% over the 180 to 650 nm primary wavelength region. 1000 nm is the MS125 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.
