Model N425


The NewDEL™ VIS fiber-coupled LED product group encompasses eight narrowband sources with center wavelengths ranging from 425 nm to 680 nm. 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.


  • Central wavelength: 425 nm
  • FWHM: 20 nm
  • Recommended fiber patch cable: Model FP63P, High NA Plastic Optical Fiber, NA 0.63
    • Optical power emitted (typical maximum): 250 mW
  • SMA905 connector (FC option upon request)


  • Photocatalytic chemistry
  • Bactericidal phototherapy
  • Dermatological phototherapy
  • Inactivation of SARSCoV-2 in saliva
  • Mycelial biomass production
