Calculate Grating Density (GD)



Formula

The formula to calculate the Grating Density (GD) is:

\[ \text{GD} = \frac{\text{GL}}{\text{L}} \]

What is Grating Density?

Grating density refers to the number of lines per unit length on a diffraction grating. It is an important parameter in optics, as it determines the grating's ability to disperse light into its component wavelengths. Higher grating density means more lines per millimeter, which can result in better resolution in spectroscopic applications.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Grating Density:

\[ \text{GD} = \frac{5000}{10} = 500 \text{ lines/mm} \]

The Grating Density is 500 lines/mm.
