For your optics lens needs, SXET will never fail in providing you with the best and highest quality of optical lenses.
And even if we’re considered to be the most reputable and most diligent manufacturer of optics lenses, you might still have a couple of questions you want to clarify before you decide on purchasing one for yourself.
Figure 1: An example of a thick optics lens
Optics lenses, lenses for short, are components used in the optical industry and are used as the building blocks of optical devices such as binoculars, microscopes, telescopes, digital cameras, smartphone cameras, and many more.
Their primary purpose is to control the light elements so that they’re able to produce the image and the intensity of light required.
Figure 2: A wide variety of materials are used for optics lenses
Optics lenses aren’t singled out to a specific type of material. As a matter of fact, you can choose from a wide variety of options for glass materials.
Manufacturers like us here at SXET usually juggle and play around many different glass materials, from borosilicate, quartz, thermoplastics like PC, PU, etc., calcium fluoride, standard glass, Trivex, fused silica, and more!
We here at SXET, though, have our innovations with the materials we use to produce optical lenses. What this means is that we’re not
Figure 3: A camera lens – one of the most common applications of optical lenses
From their term alone, optical lenses are used for optical devices and equipment. The most common applications for these optical lenses include, but are not limited to:
Of course, the application for your lens would depend on the type of lens you have. Its overall effectiveness, for instance, would be better if you’re using concave or convex lenses for eyeglasses or eyewear.
That brings us to the next section of this guide to help you understand it further – what are the different types of optical lenses?
Figure 4: Double concave lenses for microscopes and other viewing apparatus
The general types of lenses that are determined by their shape and form, and they are concave and convex lenses.
But do you know how these two (2) are different?
Concave lenses are lenses where at least one (1) side of it is curved inwards. Convex lenses, on the contrary, are lenses where the middle part of the lens is thick – and it converges, becoming thinner in both the upper and lower edges of the lens.
Other than determining them via their shape, there are also other types of determiners of optics lenses. In fact, here are a few of the
Typically used for eyeglasses and eyewear, single-vision lenses are the standard for correcting hyperopia and myopia (far-sightedness) and (near-sightedness), respectively. You know this because these would usually be the types of lenses you wear.
Camera lenses are an assembly of optical lenses that are used with a camera body, and their main purpose is to conjure images either on photographic film or other media, electronically. In simpler terms, they’re the interior of the camera glass you see from the exterior.
Wide-angle lens is another type of camera lens where the focal length is smaller than the usual. With this type of setup, the lens allows more scene included in the image or the photograph, resulting in a wider-angle type of view.
Also known as “tele lenses,” these are camera lenses that are known to have the longest focal length, even longer than the length of the lens itself. These are used for shooting objects and subjects that are kilometers away.
The term “prism” lenses have been derived from the shape that the lenses have – it’s a prism. Prism lenses are used in both the photography and optical sector.
Prism lenses function by refracting the light when it passes through the glass so that it’s directed to a particular angle.
And last in the list (but not with everything) would be bifocal lenses. These are the lenses used for eyesight that have two (2) different lens powers to help with your vision.
Figure 5: Two (2) different-shaped optics lenses
You can purchase optics lenses in varying shapes, forms, and sizes. Since it’s a type of equipment you can use for a wide range of applications, there’s no limit to the shape of optics lenses you can purchase.
Many Chinese optics lens manufacturers even offer custom units of optics lens. You can purchase the standard oval shape that are specific to cameras and eyeglasses, you can purchase triangular (prism) shapes, dome lens, spherical, ball and semi-ball, even Fresnel lenses!

The manufacturing process of optic lenses don’t fall far from how standard glass or lenses are made. In fact, here’s the usual flow of how optical lenses are made and manufactured:
The first part of the process is to manufacture or produce the raw materials of the glass product. Various manufacturers make use of different products and materials for the production or manufacturing of optics lenses.
Manufacturers and suppliers can use borosilicate, calcium fluoride, fused silica, polycarbonate (PC), polyurethane (PU), acrylic, PMMA or polymethyl methacrylate, soda-lime glass, quartz, and many more!
These products are manufactured first and cooled down, before they’re sent to the next process, which is…
After the raw products are manufactured and produced, the next step is to cut, shape, and process these materials to produce the shape or the form that’s needed by the client. It can be whatever shape or form the client wants as long as it wouldn’t tamper with the quality of the object.
Then, when the products or materials are cut and shaped accordingly, the next step is to apply the coating to the optics lens.
Depending on client need, the coating can be anything from anti-reflective (AR) coating, anti-fog coating, scratch-resistant coating, and even UV or ultraviolet coating.
These are among the best and most effective coatings for optical lenses, but, of course, whatever you’ll put would still depend on what your client needs.
Then, blank moulding is done to the optics lenses. This is a replicative process that helps with the production of high-precision components without the need to grind and polish.
After that, it’s further processed and edge-grinded according to the needs of the client. For instance, if it’s going to be a dome-like piece of equipment, then, most likely, the edge would be beveled.
Last, but most definitely not least is the process of surface finishing the optical lenses. This will determine the surface quality of the optics lens.
The process of surface finishing and polishing will depend on what the result you’re looking for is. It’s usually done using large auxiliary machineries and equipment.
This is the general structure of how optical lenses are manufactured in optical lens manufacturing plants and factories.
Not all suppliers perform this specific process to the teeth, so, it’s important to ask and inquire about this if you’re interested to know how your manufactured produces or manufactures their optical lenses.
Yes, it’s possible to print on the surface of optical lens. In fact, this is how brands mark their products as theirs, and so that other companies won’t use their products.
Laser printing is usually the process that’s done for them for the logo or the name of their brand. This is because laser printing would not tamper with the quality of the lenses; it will just produce the image, or the right amount print on the lens’s surface.
Figure 7: A newly cut optics lens without an edging finish
Yes, optic lenses can be cut, shaped, and formed according to the form and shape you wish for them to have. If you initially thought that all optics lenses just have a single shape, think again!
Take a moment to think about the different businesses in various industries that use optics lenses. Each of their needs will be different in size, shape, form, color, and even effects.
So, customizing the shapes and sizes of these optics lenses would be a necessity, especially for companies that are operating on a global scale.

Figure 8: A solar-light optics lens for cameras
Solar light optic lenses are lenses that use the energy from the sun to function. These are specialized types of lenses that have been designed and engineered to perform in accordance to the heat and energy generated and radiated by the sun.
One of the most common examples of solar light optical lenses are light concentrators. Light concentrators, in case you weren’t aware, are used to concentrate the light that comes out of the fixture.
Solar concentrators use energy from the sun so that when the light is turned on, they wouldn’t need electricity to work and function.
It’s not usually categorized as a type of optical lens because it’s not as common as the others.
Figure 9: Heat-resistant optics glass products
Yes, they are heat resistant. As a matter of fact, even standard or regular soda-lime glass are designed and made to be resistant to temperature changes. They’re thermal-shock resistant, which means they’ve been engineered not to be brittle and weak when they’re subjected to high temperatures.
And even if this is the case, several optics lens manufacturers perform heat treatments to their optical lenses so that they become more shock, pressure, and heat-resistant than what they already are.
Yes! Similar to producing optics lenses in various shapes and forms, you can also perform custom edging on these lenses. The edges they’ll be on will define their overall look and shape, and how they’ll be used by the client.
You can purchase optics lenses in various shapes and sizes, as well as custom edges, too! But, the most common edges you can have them in would be beveled edge, 2D edge, 2.5D edge, and even 3D edge.
Here at SXET, though, you can have no limits to the type of edging profile you want for your optical lens. We can produce and customize your optics lens depending on how you want and need it.
Of course, we have our Research & Development (R&D) team that can tailor-fit what you want and what you need.
We can produce a 2D-edged optics lens for you, or even bevel the edges of your optical lenses. Not to mention that we can produce custom edges for you as well!

Optical lenses are known for their properties, and they’re not strangers to them, to let you know. There are a lot of properties for optics lenses and knowing them can help you determine whether they’re the ones you really need for your application or not.
In essence, the properties of optics lenses help determine its behavior when it’s subjected to certain occurrences. The level of resistance of the optics lens would depend on how the optical lens manufacturer approached it.
Various optics lens manufacturers have different properties for their optical lenses. Generally, though, you want to see the following properties on your optics lenses:
Clear aperture, CA, for short, is known to be the area inside the lenses, which optically functional specifications and tolerances apply.
You can a clear aperture of about 92% and above of the diameter to achieve the best results.
This property or specification refers to the imperfection levels that can be seen or visually noticed on the surface of the optical lens. We’re talking about everything from digs, tiny scratches, chips, bubbles, blemishes on the coating, and more.
For your optics lenses, you’d want a surface quality of 40 to 20, or even better, if possible.
Dubbed as CT, Center Thickness is the measurement of the lenses’ thickness in the center. This actually dictates the ultimate power of the lens. Your consumers won’t need to know this, but you, as a business, you need to be aware of the center thickness, so you know the minimum and maximum capacities of your product.
As a general rule, you want the center thickness of your products to be at ± 0.1mm. You want the inconsistencies to not be too thick or too thin.
Last, but most definitely not least of this list is dimension tolerance. In the simplest definition we can give, dimension tolerance is the range of measurement that is assigned to the lens, indicating how much it can lean towards a nominal measurement.
These are the some of the most common specifications and properties you want to see on your optics lenses.
Figure 11: An image of a Fresnel lens
A Fresnel lens is a type of lens that’s comprised of many grooves that are etched into plastic. They’re used for their excellent light-gathering ability, making them useful for a wide range of applications.
Among the most common of these applications include detectors, emitters, condenser systems, magnifiers, illuminators, and many more!
