The 77302 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 precisely fit inside the instrument. 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. The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency of 80% at its blaze wavelength.
