What are Reflective Ruled Diffraction Gratings?

The Reflective Ruled Diffraction Gratings are optical components formed by mechanical etching on a reflective substrate.

Theoretical resolving power is directly proportional to the number of grooves per millimeter ruled into the master grating.

Therefore, they use the regular line structure to diffract and split the incident light.

Due to their high reflectivity the reflective ruled gratings are the core component of various optical analysis systems.

Gratings are high quality, instrument-grade gratings that are ideal when high efficiency is the primary concern in devices such as monochromators and spectrometers.

 

Advantages of the gratings

  • High diffraction efficiency: Through optimizing the line etching design and coating treatment, it ensures to achieve high diffraction efficiency within the target wavelength range.
  • Broad spectral range: People can use the diffraction gratings in different situations. They are suitable for ultraviolet, visible light and infrared bands.
  • Multiple groove densities are available for selection: It supports customizing different groove densities to achieve different resolutions and spectral coverage ranges.
  • Durable design: The grating use aluminum, gold or other highly reflective coated materials to ensure long-term stable usage.

Applications:

  • Spectral analysis: Some high-precision spectral measurement used in experiments.
  • Laser system: The grating plays a crucial role in pulse compression, wavelength tuning.
  • Astronomy: People often use the gratings in high-resolution spectral observations.
  • Research and Education: Provide high-performance optical splitting solutions for laboratory.
