Our engineering team was able to provide a combination of benefits that no other backlighting technology could match. With eight layers between the slim aluminum bezel base and overlay, we needed a compact, bright, uniform light that wouldn't sacrifice the tactile response of the switch. The design flexibility and thinness of Lumitex's Clad Flat Fiber™ allowed us to seamlessly create a custom solution. At only 0.2mm thick, we extracted light only where it was needed to maximize light output with minimal disruption to the dome switch layer. The superior performance of this user-friendly light guide resulted in our engineers being tasked to produce custom lighting solutions for a variety of their passenger control units. **Key Reasons our Clad Flat Fiber™ was selected** 1. Easily integrated 2. Thinness 3. Brightness and Uniformity [![Talk to an Expert About Your Lighting Solution](https://no-cache.hubspot.com/cta/default/2606137/91b54b85-764a-4c80-ad7c-605269a57b44.png)](https://cta-redirect.hubspot.com/cta/redirect/2606137/91b54b85-764a-4c80-ad7c-605269a57b44) ## Portable Ultrasound Equipment ### Membrane Switch Backlighting When developing the latest and most advanced model in its family, their design team presented Lumitex with an opportunity to backlight the membrane switch keypad. With its unique circuitry and limited real estate under the rubber keypad, Lumitex Clad Flat Fiber™ technology offered a great fit. Our engineers were able to easily develop a custom solution conforming to the complex geometry. The intense light of the Lumitex .3mm Clad Flat Fiber™ material was strong enough to provide superior illumination and its thin profile offered exceptional tactile response and effortless integration. Because of this, Lumitex was awarded the business.  **Key Reasons our Clad Flat Fiber™ was selected** 1. Light intensity and uniformity 2. Thin profile 3.
