5  Features of Diffractive Optical Elements


The diffractive optical elements are optical elements that can diffract light. The word “diffraction” is defined as bending, spreading out, or splitting waves when they hit an obstacle.

The Features

  • Diffractive optical elements are made of either glass or plastic.

If the element is glass, it must be coated to protect against scratches and other damage. Plastic diffraction lenses can stand up to more wear than standard glass optics because they have a smooth surface that protects them from scratching. It makes them great for high volume usage like in mass production lines.

  • A diffractive optical element can be made of any size.

It is possible to create a lens of infinite length and width by using computer programs that design lenses for specific needs. This ability makes these optics perfect for mass production because they are easily customizable on the fly without having to scrap stock or mold new pieces every time there’s an update in need.

  • Diffractive optical elements are designed to be as efficient as possible.

They allow the most amount of light through with the least amount of reflection and refraction. It is also good for diffracting more than one wavelength. It can separate infrared or ultraviolet wavelengths from visible ones without affecting them or losing any energy due to absorption.

It allows these optics to work perfectly in multiple spectrums simultaneously. The diffractive design has many benefits that make it perfect for use in mass production lines like.

  • The surface of the diffractive optical elements has a grating that creates this effect.

The most common type is known as amplitude or phase grating, which is used for different purposes. Amplitude refers to how much energy the device transmits, while phase involves where waves meet.

The grating can be designed to have specific properties for the desired result. For example, if the element is being used in an imaging application, it should diffract light so that all of the beams are focused at one point on the other side.

  • The diffractive optical elements can be designed for many different functions.

They are used in everything from medical equipment like endoscopes to projectors, microwaves, and barcode scanners. The applications of these optics are practically limitless because they work well with multiple types of light lengths, wavelengths, and energy levels.


Diffractive optical elements are a must-have for mass production lines because they allow for customization on the fly without increasing costs. In addition, their design allows them to be efficient and work in multiple spectrums at once, making these optics perfect for use in any industry where they will encounter different types of light or energy.
