Reflective Gratings

Reflective gratings are optical components with a surface surface etched with regular lines or grooves. These grooves split incoming light into multiple directions through a process called diffraction, effectively dispersing the light into its component colors or wavelengths. Unlike transmission gratings, which transmit light through the material, reflective gratings reflect the light off their surface after diffraction. They are commonly used in spectrometers and lasers to analyze light by separating it into its different spectral parts. Their precise groove patterns enable accurate control of how light is dispersed and reflected, making them essential in various scientific and technological applications.
