Optical Precision Lenses
Tight-tolerance Precision Lenses Manufacturing
precision optical lens
Over the years as optical technology progresses, high precision lenses become more and more ubiquitous in our lives. From taking selfie to investigating celestial bodies to, well, just seeing around us. They are certainly a focal point of many of our daily activities. For over four decade, our custom precision optics corporation have made optics for a variety of industries including military and defense, scientific, medical, and laser. If you need optical systems, or any other type of optical component, get in touch!
Custom Lens Manufacturer Selection
PFG has extensive lens manufacturing capabilities using all types of optical glasses, fused silica and crystalline materials including CaF2, Ge, MgF2, Si, ZnSe, ZnS and Amtir. We select the best process technology from spindle polishers, precision glasses, CNC polishers, magneto rheological finishing or a combination thereof to produce the required specifications – some subtle such as low spatial frequency, some more obviously beneficial such as low surface roughness – to achieve the required optical performance from a given material. Tight centering, truncation, high included angle or long radii – we use best practices developed from decades-long experience to achieve timely and efficient production of spherical lenses. We have a vast library of test plates and many current model Zygo interferometers, all with complete reference spheres for accurate surface measurement to offer all the types of precision opticals.
High Precision Optical Components Manufacturers
As you can see, these are available for a wide number of uses. Some of which are present in everyday life. While there are thousands of uses for lenses, each of them alters a ray of light in a specific way and has specific purposes. We work with industries including military & defense, scientific, medical, and lasers. If you are unsure which type of lens you need for your purposes, or you are looking for lenses, you are free to reach us. Our experts are on-hand to give you the perfect advice to ensure we meet your lens production needs.
What Are Optical Lenses?
These are devices people use to either focus light or disperse and diverge it. Some can manufacture products out of one single substrate or out of many different substrates to have a more complex effect.
They work due to the altering of a ray of speed when it passes through different materials. As the lighting slows down or speeds up, the angle of travel for a single ray will change. Using this quality, a lens acts to redirect.
The lens could diverge the light, reducing its focus. It could concentrate it, focusing it further, or it could perform several other tasks, especially when used in combination with other optics and optical coatings.
Types of Optical Lenses
As mentioned above, several forms exist. They are either used on their own or you can combine them for a variety of effects. An optical train is an example of this and is widely used by astrophotographers. The following details the differences in lenses.
World best optical lens company can sort components in many ways. However, many like to sort them into two broader categories – convergers and diverges. These are rounded lenses that you can use to do exactly what they sound like – converge or diverge it from or into a specific place. These types of lenses can be seen regularly 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.
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.
