NewDEL™ Fiber-coupled LEDs | OVERVIEW
Designed and manufactured by LumeDEL, NewDEL™ fiber-coupled LEDs combine high performance with simplicity to provide high-brightness sources for researchers and OEMs in a range of medical, biotech, and industrial applications. The four product groups include narrowband sources from the UV to the near IR spectral region, plus broadband sources (see below); additional wavelengths are available on request.
The NewDEL™ platform was designed for flexibility and ease of use. Each NewDEL™ model incorporates its own driver and microcontroller circuitry, so that it is ready for use right out of the package. Users have complete control over a range of parameters, including delays, triggers, pulse durations, as well as PWM frequency and duty cycle. For users comfortable with writing code, the NewDEL can also be programmed using distinct serial commands.
Because output quality is essential to the target scientific applications, the units are designed to generate high radiant power with spectrally stable output. For maximum output power, we recommend fiber patch cables with larger core diameters and high numerical apertures (NA) that optimize input coupling. LumeDEL uses PWM dimming exclusively, avoiding the spectral shifts that can be introduced by analog dimming. The design stabilizes LED junction temperature using passive thermal management, to maximize LED lifetime without the need for noisy fans that consume additional energy.
All these characteristics make NewDEL LED sources highly effective replacements for lasers and lamps in many applications for science and industry.

As Easy or Sophisticated as You Want
NewDEL™ light sources are designed to provide an easy entry point to new users of fiber-coupled LEDs while providing all of the configurability and programmability that experts expect. The unit is ready to go straight out of the box – just plug it in and attach a fiber optic patch cord. From there, configuration and operation is as easy or sophisticated as the user desires:
-
MANUAL: Intensity can be configured manually using a control on the front panel.
-
SOFTWARE CONTROL: Configure and run using a feature-rich Windows®-based GUI.
-
PROGRAMMABILITY: Serial connectivity lets users create their own code to personalize a unit’s functionality.
-
REMOTE OPERATION: Because it’s not always convenient to be in the lab during data acquisition, NewDEL can also be controlled using serial commands for integration into most programmable systems, or basic remote control by means of a terminal emulator.
This range of capabilities serves a variety of needs and capabilities.

UV [Ultraviolet]
NewDEL™ UV Fiber-coupled LEDs
The NewDEL™ UV product group combines high performance and flexibility to serve both scientific and industrial research. Because most UV applications require increased levels of output, NewDEL™ UV are designed to deliver the highest radiant power possible from a one-millimeter diameter fiber (see Table 2).
Applications
• Ultraviolet Germicidal Irradiation (UVGI) Research
• Photocuring/Photopolymerization
• UV Based Chemical and Biological Analysis

* Typical results with 1 mm core diameter, 1 m long optical fiber
**NA 0.22 High-OH, Solarization Resistant, UV Fused Silica Fiber
***NA 0.63 Plastic Optical Fiber
VIS [Visible]
NewDEL™ VIS Fiber-coupled LEDs
The NewDEL™ VIS fiber-coupled LED product group encompasses eight narrowband sources with center wavelengths ranging from 455 nm to 680 nm (see Table 3). The collection includes phosphor-coated green and amber LEDs to address the so-called green gap problem – the lack of a high efficacy semiconductor materials system for the green-yellow spectral region.
The modular design of the NewDEL™ fiber-coupled LED enables us to offer additional wavelengths beyond standard models. If you don’t see the wavelength you need, contact us.
Applications
• Antimicrobial blue light (aBL) therapy
• Fluorescence guided surgery
• Fluorescence imaging
• Optogenetics
• Photobiomodulation
• Photocatalysis
• Photodynamic Therapy (PDT)

NIR [Near-infrared ]
NewDEL™ NIR Fiber-coupled LEDs
The NewDEL™ NIR product group of fiber-coupled LEDs combines narrowband output at wavelengths targeting key NIR applications (see Table 4). As with other narrowband models in the NewDEL™ incorporates controller and driver circuitry and uses PWM dimming exclusively to prevent wavelength drift. Contact us if you need wavelengths not already listed in the table below.
Applications
• Fluorescence Guided Surgery
• Functional near-infrared spectroscopy (fNIRS)
• NIR spectroscopy (NIRS)
• Photobiomodulation
• Photodynamic Therapy (PDT)

BB [Broadband]
NewDEL™ BB Fiber-coupled LEDs
The NewDEL™ BB product group is designed for spectroscopy applications. It encompasses two white light sources with different color temperatures and CRIs, as well as a continuum source (see Table 5). Sources deliver higher efficiency output than omnidirectional mercury arc lamp sources. As with all other members of the product family, each NewDEL™ Broadband model incorporates its own driver and microcontroller circuitry and offers three options for configuration and control.
Applications
