F.A.Q.

Technology

How does the Luxexcel technology work?
The Luxexcel technology is an inkjet-based 3D print technology which builds lenses droplet by droplet. From a liquid material, small droplets are jetted to build the required ophthalmic lens shape. Because we let the droplets merge before they are cured, we obtain very smooth lens surfaces without any post-processes. We are able to create very accurate lenses because we use extremely small droplets, and we are able to print rapidly because we jet many droplets at the same time. To learn more about our process, please refer also to our video gallery.

What is your business model?
Luxexcel will provide a full turnkey solution to ophthalmic labs. This in-lab solution includes a 3D printer, consumables, design software, print process and full service and support. We provide the full turnkey solution in order to make optimal make use of the 3D print capabilities. The lab will pay on a click fee basis and will make a volume commitment to Luxexcel. The equipment remains property of Luxexcel.

Who will have access to this technology?
Our primary customers are ophthalmic labs. We will provide them with our enabling 3D print technology solution consisting of hardware, consumables, software and full support. Through the labs, we will provide full customization solutions to opticians and optometrists allowing them to make full use of custom lens designs and better serve their customers.

When can I have a machine?
We are currently taking orders from ophthalmic labs, if you are an ophthalmic lab and want to join us on this exciting journey, please reach out to us to discuss the possibilities.

What is the pricing for a machine?
We will not be selling machines. If you would like to have a machine in your ophthalmic lab we make them available based on a click fee model. Please contact us if you would like to discuss the possibilities for your ophthalmic lab.

What products can be 3D printed?
Initially, the focus will be on low volume high-value products, slab-offs, prisms, high diopters, multifocals etc. In 2018 more products will become available.

What ophthalmic lab can provide me with lenses?
For now, we deliver from our own facility for selected test market purposes only and make sure we stay aligned with the latest market trends. In Q4 2017 we will have our set-up available from different labs around the globe (The US and Europe) from where we start to deliver to selected dispensing optometrists.

I am an optician, can I get lenses?
We work through ophthalmic labs and our first machines will be installed in Q4 2017. We could connect you to an accredited lab in Q4 2017. If you would like to stay up to date please subscribe to our newsletter.

Can I get some lenses to test?
We do not sell lenses directly. Starting Q4 2017 we will provide our technology through selected ophthalmic labs. If you are an ophthalmic lab and would like to know more about our technology solution please contact us.

Do you provide prototyping for other industries like lighting and automotive?

All focus is on the ophthalmic market

Material

What materials do you use?
Luxexcel developed its own UV curable material. The material properties are in similar to common eyewear materials.

What is the refractive index of the material?
Our material has a refractive index of 1.53

What is the Abbe value of your material?
Our material has an Abbe value of 45

What is the weight of your material?
Our material has a weight of 1,15g/cm3

Are 3D printed lenses at ISO/ ANSI level?
We comply with ISO 8980-1:2004 Focal Power tested by Colts Laboratories. You can review the report here. We take in account ANSI standard.

Do 3D printed lenses pass the FDA drop ball test?
Yes, our lenses do comply with the FDA drop ball test, including both the big and small ball.

What are the operating temperatures?
Between -20° C and + 50° C ( -0.4° F / + 140° F).

What are the values for transparency?
Transparency: 99.4% (per mm)
Haze: 0.1%

Coating & Edging

Coating compatibility
Luxexcel lenses are compatible with various coatings typically used in the ophthalmic industry. Through partner companies we are compatible with:

• Hard coats/Anti-scratch coatings
• Blue light / UV filter
• Anti-reflective coating
• Tinting
• Mirrors

We are currently developing:

• Polarization
• Photochromic

Can your lenses be edged?
Our process is compatible with both stone-based and tool-based edging processes.

Lens Design

Do you have lens design software?
To make use the benefits of 3D printing Luxexcel has developed a lens design suite called 'VisionMaster' which allows ophthalmic labs to create their lens designs. The software is developed to design lenses which are difficult to manufacture and is ideal for designing specialty lenses.
