Guide to The History and Uses of Diffractive Optical Elements

Diffractive optical elements have come a long way since their early beginnings in the 19th century. But, have you ever thought what were the stages of developing them? Let us know about them in detail.

The history of diffractive optical elements:

The history of diffractive optical elements can be traced back to the early 19th century when Scottish physicist Sir David Brewster developed a theory of light diffraction. This theory proposed that when light strikes an object, it is scattered in all directions. However, some of the light will be reflected in a specific direction, depending on the angle of incidence and the shape of the object.

This effect is known as diffraction. In 1821, French physicist Augustin-Jean Fresnel expanded on Brewster’s theory and showed that curved surfaces could produce even more pronounced diffraction effects. These early theories laid the foundation for the development of diffractive optical elements.

The Findings Later On:

In the late 19th century, diffraction was exploited for commercial purposes, with the first diffraction grating being patented in 1885. This type of optical element is used to split light into its component wavelengths, making it possible to study individual spectral lines.

The first lens fabricated using a diffractive optical element was created in 1957 by Yuri Denisyuk, a Soviet scientist working at Leningrad University. Denisyuk’s lens was made using a photographic process and had a spherical surface with a concentric zone plate structure.

The Additional Developments in The Field:

This revolutionary design paved the way for the development of aspheric lenses, which are now used in a wide range of optical applications.

1.    The First Hologram:

The first hologram was created in 1947 by Hungarian physicist Dennis Gabor. Gabor’s work was motivated by the need for a higher-resolution electron microscope, as the existing technology at the time was limited by the diffraction of electrons.

He developed a new type of microscope that used lasers to illuminate the specimen, which resulted in a three-dimensional image. This groundbreaking work laid the foundation for the development of modern holography.

2.    The First Laser:

In 1960, the first laser was invented by American scientists Theodore Maiman and Arthur Schawlow. The technology behind the laser was originally developed in the 1930s by Hungarian physicist Leo Szilard and German engineer Rudolf Ladenburg.

However, it wasn’t until Maiman built the first working laser that the potential of this new technology was realized. Lasers have since found a wide range of applications in both scientific and commercial fields.


Today, they are used in a wide range of applications, from microscopy to telecommunications. As new and improved technologies continue to be developed, the potential uses for diffractive optical elements are sure to grow.
