Model W4270


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. 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.


  • White LED
  • Correlated Color Temperature (CCT): 4200K Color Rendering Index (CRI, Ra): 70
  • Recommended fiber patch cable: Model FP63P, High NA Plastic Optical Fiber, NA 0.63
    • Optical power emitted (typical maximum): 240 mW
    • Luminous power emitted (typical maximum): 80 lumens
  • SMA905 connector (FC option upon request)


  • VIS spectroscopy
  • Colorimetry
  • Machine vision
  • Microscope illumination
