What are Reflective Holographic Gratings?

 

Reflective holographic gratings are advanced diffraction gratings used to reflect and disperse light with exceptional precision.

Holographic gratings are formed by an interference fringe field of two laser beams whose standing wave pattern is exposed to a polished substrate coated with photoresist.

Holographic gratings can produce less stray light compared with the straight-line gratings.

They can also produce up to 3600 grooves per millimeter to achieve a greater theoretical resolution.

These properties make them a preferred choice in high-performance optical instruments.

Advantages

 

  • High Spectral Resolution– Minimized stray light ensures accurate wavelength separation. Therefore, they can achieve a greater theoretical resolution.
  • Superior Surface Quality– Produced by holographic techniques for smoother grooves. This makes the effect more precise.
  • Durable and Stable– Designed to maintain optical performance under demanding environments. Also, they can be used in different environments.
  • Versatile Configurations– Available in different blaze angles, groove densities, and coatings to match various wavelength ranges. Therefore, people can choose them according to the using requirments.

Applications

  • Spectroscopy – For high-resolution spectral analysis in UV, VIS, and IR ranges.
  • Laser Systems – People can use them to control, shape, and stabilize laser beams.
  • Telecommunications – For wavelength division multiplexing (WDM) and signal processing.
  • Scientific Research – In astronomy, plasma diagnostics, and analytical chemistry.

Why Choose Reflective Holographic Gratings?

Compared with the traditional gratings, reflective holographic gratings deliver higher optical efficiency, lower scattered light, and more stable long-term performance.

Their precision design ensures reliable results in both laboratory and industrial applications.

And their efficiency is usually much lower than that of similar straight-line gratings.
