Newport MKS 77250 Monochromator Grating, Ruled, 150 l/mm, 800 nm blaze, 425-1600 nm 77317

The 77317 Grating Assembly is designed for installation into the Oriel® 77250 Hand Operated Monochromator. 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 80% at its blaze wavelength. The frame has a tab that allows the grating to be inserted or replaced inside the monochromator 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.
