LUXeXcel logoJust last month, Netherlands-based LUXeXcel announced a new partnership with Edmund Optics to bring 3D printed plastic optics to the photonics industry. LUXeXcel‘s announcement then just got the ball rolling, as now they’ve just released news of progress on another front, as they’ve teamed up with a second optics company in another working partnership. Massachusetts-based Lambda Research, which designs optical design and illumination software, including their flagship TracePro software, is now working with LUXeXcel toward the production of custom-textured lens arrays.

“LUXeXceL’s printing process and TracePro are complementary for optics designers in their quest to design the best solution for every project, not having to compromise with standard, less optimal, products,” said Richard van de Vrie, president and founder of LUXeXcel. “[This provides] optical designers with full control over the light distribution, ensuring speed and reduction of project costs.”

By bringing these technologies together, the aim is to allow for “mass customization” of plastic-made optical components, including textured lenses, that can be created to exacting specifications.

“TracePro software simulates the distribution of the light and the luminous intensity,” said Lambda Research’s VP of Sales and Marketing, Michael Gauvin. “This will give designers insight into how the light distrbution of their printed product will look like.”

A “high-quality, commercially viable” lens array was created to showcase the integrated benefits of the partnership. Using TracePro Texture Optimizer, the design was created to diffuse light across the array due to texture and depth variations. TracePro is able to integrate LUXeXcel materials into its design consideration, so designers can see the qualities of the materials and how they will affect the product’s light output.

Once converted into and exported as a CAD file, LUXeXcel took the lead in 3D printing the pieces. The entire iterative process is shortened to a matter of days, a benefit of additive manufacturing enjoyed through a variety of industries where lowering both costs and lead times are hugely beneficial.

“Tlambda-logo-newhe function of our created lens array is to provide randomized uniform light output with light either propagating through the part or reflecting off the part. The texture applied to the part is specific to take a non-uniform propagating light output and create uniform light,” said Lambda Research’s Gauvin. “This is achieved by varying the texture in such a way that strong light areas are reduced and weak light areas are supplanted by moving light from the strong light areas to the weaker ones.”

This partnership should provide some interesting results through the combination of the companies’ complementary technology offerings.
