What Are Optical Lenses?
Optical lenses are devices employed for the manipulation of light, either by focusing or diverging it. They can be composed of a single substrate or a variety of substrates, depending on the desired outcome. The alteration of the speed of light as it passes through different materials is the principle by which these lenses function. As the velocity of light is modified, the angle at which it travels is correspondingly altered. Through this quality, a lens serves to redirect the light.
These lenses can be utilized to diverge light, reducing its focus, or to converge it, intensifying its focus. Additionally, they are capable of performing a variety of other functions, particularly when utilized in conjunction with other optical elements and optical coatings.
Different types of optical lenses
As described by suppliers, optical lenses are available in various forms and can be utilized individually or in combination to achieve a plethora of effects. An example of this is the telescope, which is widely employed by astrophotographers. The following information serves to detail the distinctions between lenses. Should you have any inquiries, please do not hesitate to reach out to us, the premier precision lens supplier, PFG Optics.
It is common to categorize them into two broad groups: convergers and divergers. These are spherical lenses that serve the purpose of converging or diverging light to or from a specific point. These types of lenses can be commonly observed in everyday life.
A diverging lens allows lighting to distribute over a wider area. One example of this that is frequently observed is in a projector at the movies. There is a parallel beam of light that goes through the projector. The projector then spreads those light rays out into the distance across the screen.
So, next time you are catching the latest action flick, look back at where the movie is being projected from and observe how it is spreading out. If you need optical systems, or any other type of optical component, get in touch!
Oppositely, using a converging lens brings lights over a larger area into convergence, or a point of focus. Your most day-to-day example of this is a magnifying glass or a microscope. The converging lens bends the parallel rays from what you are magnifying so they converge in a sweet spot for your eyes.
Hence why you have to move it up and down sometimes to get the perfect picture for you. The most common place you can find these kinds of lenses are in spectacles or the eyes themselves. They focus rays into a small space. If the eyes are an imperfect lens, the spectacles reorient lights before they hit the eyeball to correct them. Our US precision lens company manufactures sophisticated precision optics for many uses.
