Ruled grating

Types of ruled grating

Ruled grating, also known as ruled gratings, are optical devices used in spectrometry for diffraction. The ruled gratings consist of thousands of lines that are etched or ruled onto a reflective surface. They are used to disperse light into its constituent spectrum. The light is divided into different colors based on the wavelengths. The types of ruled gratings are as follows:

• Transmission Gratings

  These types of grating allow light to pass through the surface. They are mounted on transparent substrates. The light is diffracted into various spectrums when it passes through the ruled grating. The transmission grating is further divided into two: Transmission Ruled Grating and Transmission Diffraction Grating.

• Reflection Gratings

  These ruled gratings reflect light instead of transmitting it. They are the most commonly used type of ruled grating. They are suitable for applications involving visible and near-infrared wavelengths. The light is diffracted and reflected back at specific angles. Reflection ruled gratings are also classified into two: First-order Reflection Grating and Higher-order Reflection Grating.

• Blazed Gratings

  Blazed ruled gratings have a saw-tooth profile. The profile is designed to concentrate the light energy into specific diffraction angles. The design allows for greater efficiency at particular wavelengths. The blaze angle and wavelength are application-specific. The gratings can be made for either transmission or reflection diffraction.

• Ruled and Holographic Gratings

  Ruled gratings are produced by mechanical ruling. The process creates a regular pattern of grooves. Holographic gratings are made using laser interference patterns. They allow for high precision and efficiency in light diffraction.

• Variable Groove Density Gratings

  These types of grating have sections with different groove densities. The varying densities enable the dispersion of a wide range of wavelengths. They are useful in applications requiring flexibility across different spectral ranges.

• Phase-Varying Gratings

  Phase-varying ruled gratings manipulate the light waves' phase front. The manipulation leads to efficient diffraction without relying solely on the amplitude variation of the grooves. They are mostly used in advanced optical systems.
