Newport MKS MS125 Grating, Ruled, 600 lines/mm, 370 nm blaze, 270-1000 nm range 77414

The model 77414 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 of 75% 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.
