Reflective diffraction grating

The effects of diffraction are becoming more and more popular by the day. With it’s entertaining visuals, you can understand why it’s taking the nation by storm. With all this hype you may be asking yourself, “What is diffraction anyways?”. Diffraction is defined as the process by which a beam of light waves is spread out as a result of passing through a narrow aperture or across an edge or “grating”. As the light passes through this grating, each beam of light is split into its individual spectrum of colors turning white light into a full rainbow spectrum. Pretty cool, huh?

You can see by just looking at a single light source; the diffraction effect will create a burst of colors. Now imagine looking at hundreds of fireworks, lasers, and holiday light and you can see why diffraction glasses have really become so popular.

The discovery of light diffraction goes back to when Sir Issac Newton observed a beam of sunlight pass through a glass prism. What he discovered is that light is made up of a spectrum ranging from 7 different visible colors. This is the exact same visible spectrum that you see when wearing diffraction glasses today! During this time a man by the name of Francesco Maria Grimaldi, also observed and characterized what would soon be known as light diffraction. Francesco is also known for coining the term “diffraction, ” from the Latin “diffringere, ” meaning ‘to break into pieces.’ Fast forwarding some years and a scientist named James Gregory observed the first form of diffraction grating, by studying the light break up caused by bird feathers. Throughout the years, their observations were studied and molded into the theories and laws, which govern, light diffraction as we know it today! Pretty trippy.

According to physics, diffraction is the spreading out of waves. These waves can vary from water, sound, radio, or light, as they pass around an obstacle or go through an opening. This is the main idea when determining if diffraction is being observed. Some everyday ideas of diffraction are water waves spreading out as they move around an obstacle, such as a large rock in the middle of a stream. These waves have been diffracted around the rock that is in the way. Maybe this example will be more familiar. Have you ever observed the back of a CD when light hits it? The rainbow pattern that is created really is diffraction in the works. The key to providing an awesome and stimulating visual experience is having light waves that ordinarily will not bend around corners, but will be diffracted when they pass through tiny openings. Now you have yourself an awesome pair of diffraction glasses.

Another cool feature about diffraction is that you can tell a ton of information simply by studying the spectrum of colors it produces. Some knowledge that can be gained by observing diffraction is how hot the object is, how fast it’s moving, or what it’s made of. When looking at objects, such as distant galaxies, this kind of information can be very beneficial. Realistically though, you are most likely buying a pair of these glasses for entertainment purposes and could care less about the temperature of a star millions of light years away.

So what makes other diffraction glasses better than others? The answer is based on what you are looking to do with these glasses. Some might enjoy a softer effect to wear during the day and for long-term use. While most people look for the most intense effect created by multiple layers of material or lenses. If you are looking for rave or festival glasses, we highly recommend an intense effect as found with our 3D Diffraction Glasses, or Matrix Glasses. Since we manufacture these glasses we have the ability to customize every aspect of the design. Keep in mind though, the more layers of diffraction you have, the less light passes through the lens creating a more blurry view. The best diffraction glasses at the end of the day are judged on a personal perspective. Luckily, GloFX offers tons of dimensional eyewear options and customizable designs as well as Bulk and Wholesale Diffraction and Kaleidoscope Glasses. Take a look around our store, you won’t be disappointed.
