Creating a collimated light beam for f.lens

Summary of the project

Smartphone flashes can’t light objects that are far away. They cast a wide beam to evenly light close subjects. But what if you need a collimated light beam? With f.lens you can collect light rays and generate a brighter light beam. Able to light up subjects up to 10 meters away.

The challenge

Can you use your smartphone as a flashlight? It didn’t seem possible until the team started lab-testing their smartphones. It was possible, now they just needed a manufacturing process to rapidly create their products.

Problem definition

Every smartphone has a flashlight function. But it is just not good for lighting up faraway subjects. As such the f.lens project was created. The idea for the f.lens came up because the creators often go hiking in the hills to enjoy beautiful sunsets. Different questions came to mind, like “Why can’t a phone be a real flashlight?”. The creators took this idea to their lab and tested the limits of their smartphones. They found out that is wat actually possible.

At Luxexcel we 3D printed the lens for the f.lens team. This optic fits in another 3D printed part, the host. This led to a small, lightweight solution that you can take along with you wherever you go. 

The solution

f.lens is the first booster for your smartphone flashlight. With it’s far-reaching beam you can light up objects that are far away. F.lens amplifies your light by ten times. Besides, it’s easy to take with you as you can magnetically attach it to your smartphone and it fits on your keychain.

About f.lens

“Flens” is the conjoined effort of three young Italian professionals, namely Marco (27), Ivan (27) and Alessandro (20). They have combined their knowledge about engineering, web development and media content productions to launch the f.lens product. They have done a Kickstarter project before (Relio), a professional photographic illuminator, with great success.

Unique project features

  • No upfront investements: thanks to the zero need for tooling, no working capital was lost to molds or tooling parts.
  • Fast delivery: following the very short lead time of only 5 business days, the f.lens team got the custom parts delivered in days rather than weeks or even months, enabling them to speed up their product development process.

Luxexcel's 3D printing technology enabled us to make use of rapid prototyping for optics. With this unique technology we were able to refine our product and iterate until we were satisfied with the product design of f.lens.
