Have you ever observed how light from a flashlight can spread out and appear to shine in multiple directions? This sort of light isn’t great, because it does not light up exactly where you want it to. When the light is everywhere, it can be difficult to see clearly. And that’s where the es come into play! These special lenses help light travel in a straight line, focusing that light so that it is more useful.
For instance, a collimating lens is a lens that gets the light waves to run parallel. Parallel light waves won’t scatter and disperse when this is the case. Instead, they can traverse long distances without detracting from each other or getting muddled up. That helps you see things much more clearly, especially from a distance.
All collimating lenses are critically important elements of many different optical systems. They are commonly employed in lasers, which are devices used in numerous professions and fields. For instance, in laser cutting machines, collimating lenses are used. These machines slice and dice metal and plastic with precision. The lenses focus the beam of the laser so that it can work its magic.
In addition to helping with cutting, collimating lenses also help focus light where it otherwise wouldn’t go. But this is especially helpful when you want to view faraway objects more clearly. It is what allows you to have a clearer view of what you’re looking at (in terms of a distant star or of a small detail in a picture) by rendering the light waves parallel.
They keep the laser beam focused as it propagates over long distances. In the absence of a collimating lens, the laser beam can diverge and become weaker as it travels. This spreading can also render the laser less effective, such that it isn’t as useful for cutting or other purposes. A collimating lens keeps the laser powerful and focused.
The second function of collimating lenses is to limit the light lost during propagation. If the light waves aren’t perfectly parallel, some of them may get lost along the way. This means you are not using your laser to its maximum potential. Collimating lenses ensure that the light waves remain in-phase, maximizing laser utilization for a faster and more effective output of work.
Imagine, pick, for example, looking through a microscope at a drop of pond water out of which float, under the lens, tiny creatures. Non-parallel light waves can scatter and obscure the specimen. That scattering can generate a blurred image that is not easy to manipulate. A collimating lens can help ensure the light waves are parallel and thus offer a much clearer and detailed look at the specimen. This precision is important in research, where small details can have large implications.
