MS125 Grating, Ruled, 1200 lines/mm, 975 nm blaze, 350-1000 nm range

The model 77463 Grating Assembly is designed for installation into the Oriel^® MS125 Spectrograph. This 30 x 30 mm grating comes pre-aligned in its own frame, allowing it to precisely fit inside the instrument. The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency exceeding 70% at its blaze wavelength.

The frame has a tab that allows the grating to be inserted or replaced inside the spectrograph without touching its surface. Each grating comes with a protective cover and is labeled with the model number, making interchangeability and storage simple. Note that the instrument will require recalibration after replacing the grating.
