Introducing the

NewDEL™ Fiber-coupled LED

Meticulously engineered photonic tools built to advance the goals of our customers, whether they are forging new paths in scientific discovery or implementing an ongoing project.

Illuminating Innovation

The flexibility you want, the performance you need

When it comes to applications like spectroscopy, optogenetics, and photodynamic therapy, the quality of the light source directly impacts the value of the results. As users of photonic instrumentation increasingly switch to fiber-coupled LEDs, they look for sources that produce stable, high-power output, at a range of wavelengths. NewDEL™ fiber-coupled LEDs meet those performance goals while also empowering researchers and innovators to target operation to each project, whether that’s manual configuration or fully automated remote control. With being engineered for customization, they can also be tailored to meet specialty requirements upon request.

Meet the NewDEL™ fiber-coupled LED

The NewDEL™ product groups of fiber-coupled LEDs were designed to deliver high performance operation from a system tailored to the user.

  • High output power – High-power LEDs selected to maximize fiber coupling efficiency, advanced thermal engineering to ensure stable output
  • An integrated driver/controller – Ready to go, out of the box
  • Configuration options – Through a feature-rich Windows-based GUI or programmed using distinct serial commands
  • Choice of operating modes – PWM, pulsed, and trigger modes

Collimating Lens Assemblies with Adjustable Focus for High NA Fiberoptic Patch Cords used with Fiber-coupled LEDs

Manchester, NH, January 16, 2024 – LumeDEL LLC introduces fiberoptic collimating lenses optimized for fiberoptic patch cords with high numerical aperture (NA) up to 0.63. Very high NA, multimode optical fibers provide the best optical coupling efficiency with LEDs to deliver maximum output power.  Standard fiberoptic collimators are designed for low NA optical fibers, like NA 0.22, which results in significant power loss if used with high NA optical fibers. Collimated beams are very useful in laboratory setups with fiber-coupled LEDs, because the beam diameter remains fairly constant to work with other optical components and avoid excessive beam expansion. LumeDEL offers two models using high NA aspheric lenses, the CL12G with a lens diameter of 12.5 mm and the CL30G with a lens diameter of 30 mm. Both feature an SMA905 connector and user adjustable focus to get the best beam collimation at the operating LED wavelength. The lens material is molded glass and can function over a...

Fiber-coupled LED Features a Broadband Spectrum Extending from The UV to The NIR for Applications in Spectroscopy

Manchester, NH, November 8, 2023 – LumeDEL LLC introduces the NewDEL™ Model X3312 Fiber-coupled LED source that employs a unique phosphor-coated UV-LED to emit a broad spectrum, 330 nm -1100 nm, for applications in spectroscopy as a replacement for halogen lamps. If the UV peak is not needed or deemed intrusive, it can be blocked by a long pass filter that only passes VIS-NIR light, thus providing a continuous and balanced spectrum without peaks.The Model X3312 is a compact, fully integrated product which incorporates its own driver and microcontroller circuitry. A separate driver/controller module is not required. Device operation can be performed through a feature-rich Windows-based GUI or personally programmed using distinct serial commands.The NewDEL™ product line of fiber-coupled LEDs includes three different broadband sources as well as 17 narrowband models with peak wavelengths from the UV to the near-IR spectral regions. The models offer complete configurability, from a...
