Frequently Asked Questions

General

Luxexcel is the pioneer in 3D printed lenses. We have developed a complete 3D printing solution and own many patents in this space. We focus on providing technology to 3D printing lenses, our customers use this technology to 3D print regular lenses, difficult lenses, lenses with active features included and smart glasses. The Luxexcel VisionPlatform™ includes the 3D printer, software and lens printing material which works together to create our lenses. Our technology is ideal for combining smart technology with lenses to create the eyewear of the future.

Our technology offers a revolutionary new approach to lens manufacturing. 3D printing allows production without the need to keep inventories. With 3D printing, one can also make fully customized lenses for many applications. The benefit of 3D printed lenses is a more efficient and eco-friendly way to create lenses and in addition enable lenses which are difficult to manufacture with legacy lens technologies. Our technology is ready to combine smart technology with a prescription lens.

What if you could take the functionalities of your smartphone and place it in your glasses by combining prescription lenses and integrated smart technology to enhance the function of the lens? The Luxexcel printing platform can be used to create different types of lenses. Our lenses do not require polishing after printing.

We have offices in Europe and the USA: The Netherlands, Belgium and Atlanta, GA, USA.

Since 2009. Beginning in 2017 we have focused on ophthalmic lenses. Starting in 2020, we will address the intersection of the eyewear and consumer technology industries.

Independent investors. No eyewear industry companies are owners. We work closely with both the eyewear and the smart wear business.

The company was founded by people from the lighting industry. They started in 2009. In 2017, we identified it was possible to make ophthalmic lenses and since then, we have developed a skillset in commercially ready ophthalmic lenses. Today, the company has achieved our objectives to enable our customers to make good quality prescription lenses every day on a commercial scale. We are now working with several major tech companies to create the eyewear of the future.

It’s a small world and we talk and work with many companies. We are seeking people and companies who share our passion for innovation including technology companies focused on innovative products and eyewear companies. We find our technology is the best fit for technology companies, AR/VR companies, smartwear/hardware developers, ophthalmic Labs who sell to doctors, consumer brands, and large ophthalmic or technology retail chains. We are open for other partnerships which fit our business model.

We have an extensive portfolio of patents covering all aspects of our technology. We started with developments in 2009, so we were very early in this space and therefore own the key patents in this space.

Luxexcel is a private company with both financial and strategic shareholders.

Technology

Our technology builds lenses droplet by droplet. From a liquid through droplets the required shapes are built. The droplets are cured individually. The machine moves a stage underneath the print heads. We are precise because we use very, very small droplets, we are quick because we use many droplets at the same time. Because we let the droplets merge before locking them in place, we obtain very smooth surfaces. Our lenses do not require blanks, taping, blocking, generating, polishing, lasering, deblocking, or de-taping.

We meet ISO/ANSI/FDA standards for prescription lenses, but we can do more: with 3D printed lenses we can make things not possible with legacy technology. Examples of this are unique products such as integration of technology inside the lens and creating unique lens designs.

No. This is one of the key advantages to the process. Straight of the printer, the lens is smooth and ready to be coated, if that is preferred.

We can create precise lenses because we use extremely small droplets, and we are able to print quickly because we jet many droplets at the same time. This process allows us to obtain very smooth lens surfaces without any required polishing.

We can discuss your project, but many sizes are possible with customization.

We certainly can. We can print on many different types of materials from CR39 to PC, to Glass to PMMA and many others. Sometimes additional interface layers are required to maintain adherence.

Our Luxexcel VisionClear™ materials family is compatible with standard ophthalmic coatings.

We make prescription lenses for smart glasses not the complete end-product. We can make all kind of prescription lenses, also types that cannot be made with traditional manufacturing technology. The benefit of 3D printed lenses for smartglasses is that we can integrate electronics, LCD screens, active films, waveguides holographic structures, LED lights, sensors, camera’s and many other things into a prescription lens. We enable the combination between prescription and smart into one unit combining the best properties of both. This will enable smartglasses that look like regular glasses.

Our lenses are similar in cost to legacy lenses if traditional technology can even make the lenses our technology enables.

Partnerships & business development

Luxexcel is a technology development company. We provide turnkey solutions to companies seeking a solution to make lenses.

Once we have the technology focused to a specific lens product, we provide hardware, software, materials and process to enable our customers to produce themselves or have their suppliers produce it for them.  We do occasionally make examples for our partners as we develop a lens together. This allows us both to modify and learn if our technologies are a good match for a certain commercial product.

We work with our partners in joint development projects. This includes an initial discussion and review of the product to determine if it is printable. We may then agree together to create some of the items to review as a first step. Then we move forward to creating the final product with the goal of printing the product commercially in an ongoing basis in our printers.

This depends widely on the project you are seeking to create with 3D printed lenses. Our lenses are similar in cost to traditional lenses if traditional technology is compared.

We do not sell our printers. We provide a turnkey solution including the VisionEngine™ printer, VisionMaster™ software and VisionClear™ family of printing materials. The printer used to create the ongoing products may be housed at your facility or at ours and is always the property of Luxexcel.

We do not sell our ink/printing material. It is created to only be used in our patented printing process.

We provide a technology to 3D print ophthalmic lenses. We do not make smart glasses directly for end-users. We integrate third party smart technology into prescription lenses. If your project has a commercial path clearly defined but still needs a smart frame or a smart film to bring it all together, we may be able to help source items to combine with our lenses to make it a reality.

We print shapes and we can print many different kind of lens designs. We currently work with a limited number of designs but it is possible to expand to any progressive design.

We will print our own PAL design through a partnership with a company which has optimized designs for 3D printing. We could provide this design as part of our VisionPlatform(tm).

We do not sell lenses. We will provide a VisionPlatform™ to make your own lenses. The pricing per lens will depend on the volumes you are planning to print. Please contact us to discuss the lens type you would like to print. We are happy to discuss this with you.

Material specification

We have the Luxexcel VisionClear™ material family. The material for ophthalmic lenses has an RI=1.5225, abbe 45, weight 1,15g/cm3.

We are ISO certified 8980-1 with a certificate from Colts labs in Florida.
We are compliant with FDA drop ball testing including both the small and the big ball. We meet ANSI standards for prescription eyewear in the US.

With accelerated lifetime testing we have obtained good results for 3 years. Since the average consumer changes lenses every 2.5 years, our lenses should meet the customers’ lifetime of that prescription. This is comparable to traditional lenses.

Luxexcel 3D printed lenses are compatible with various coating processes, such as Anti-reflective-, hard/anti-scratch, tinting and UV blocking coatings. Most of these coatings are applied by using spin-coating technology, while others may use dip coatings.

Our process is compatible with both stone-based and chisel-based processes. Our customers report no issues with using most traditional edgers on standard settings.

Not currently. This is on our VisionClear™ material family roadmap. Our current index is 1.5225 and has a great Abbe value of 45. Because we can modify and customize the shape of the lens, we can create the best form factor for each product which may include a thinner profile than legacy manufacturing.

We have a family of materials we can print and we are developing even more materials.

The advantage of our process is that we can stop and add items such as foil, electronics, etc… and resume printing. This allows the addition of a prescription lens power to a foil, or electronics designed to be placed in front of your eye. All new foils, or electronics will require a review by our team for feasibility with our technology.

We tested adhesion to several materials, including CR39 to PC, Glass to PMMA, and we can achieve adhesion to different materials.

With 3D printing, there are many more options also from a design and fabrication perspective as compared to legacy prescription lenses.

We have the Luxexcel VisionClear™ material family. The development of higher index materials is on our material family roadmap. For now, we have one material optimized for ophthalmic lenses with a 1.5225 index. We customize prescription lenses in many ways so a thinner profile may be achievable for your design even without a higher index. The abbe value of 45 makes this index particularly attractive for good optics not often found in higher index materials.

Today, our process works with one material which meets the standards for ophthalmic/prescription lens fabrication. On our roadmap, the launch of novel optical lens materials is planned, so gradient refractive indices are possible, in time. We believe 3D printing is the way to achieve stacking or layers with multiple indices and we are aware of the enormous potential of this ‘holy grail’ in optics. We share your enthusiasm to reach this goal. This would be an excellent development project with a partner company.

We currently print a prescription range of -6 dpt to +6 dpt cyl with up to 1.5 diopters of cylinder to combine with your smart technologies. This range can be expanded on an as needed case basis.

In general, you can divide our current portfolio into three main product groups:

Traditional: lenses which are like what you can make with traditional technologies or are challenging to make with legacy technology

Feature lenses: lenses with the integration of simple electronics such as a sensor or integration of an active foil such as electrochromic or even switchable powers.

Smart lenses: lenses which combine prescription lenses with smart features as in augmented reality.

We pass all the required ISO, ANSI and FDA requirements for prescription lenses. We have certificates by COLTS laboratories an independent US-based testing facility for ophthalmic lenses. Our lenses comply via COLTS testing with ISO 8980-1:2004 Focal Power, EN 166:2001 Minimum Robustness (22-inch drop ball), ISO 8980-3 Transmittance, FDA 50-inch drop ball, UV Transmittance. Our lenses are frequently tested in the lab against ANSI lens power requirements and found to be compliance for dispensing to patients.

No our material does not show birefringence
