77250 Monochromator Grating, Ruled, 2400 l/mm, 275 nm blaze, 200-500 nm

The 77308 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 exceeding 65% 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.
