NewDEL™ BB Fiber-coupled LEDs
The NewDEL™ BB [Broadband] 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
• Spectroscopy
• Industrial acceptance testing
• Materials research
• Process control
• Spectral reflectometry
• Colorimetry
• Thin film metrology
• Plasma processing endpoint detection

The Advantage of Broadband LED Sources
Broadband LED sources provide wide spectral coverage, making them ideal for spectroscopy, fluorescence imaging, and teaching labs where multiple wavelength ranges are required. LumeDEL’s NewDEL™ Broadband models, including the X4010, deliver stable, long-life illumination that replaces bulky, short-lived arc and halogen lamps.
Why Broadband LEDs Matter:
-
Wide Spectral Range – UV to NIR coverage for absorption, emission, and transmission studies
-
Stable Output – Consistent illumination improves accuracy and reduces recalibration needs
-
Long Operating Life – Thousands of hours of reliable performance vs. frequent lamp changes
-
Compact Design – Saves valuable bench space compared to traditional lamp systems
-
Environmentally Safe – Mercury-free and energy-efficient
By combining stability, spectrum coverage, and reliability, NewDEL™ Broadband LED sources empower researchers with modern, cost-effective alternatives to outdated lamp technology.
