The NewDEL™ VIS fiber-coupled LED product group encompasses eight narrowband sources with center wavelengths ranging from 455 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.
SPECIFICATIONS
- Center wavelength: 495 nm
- FWHM: 20 nm
- Recommended fiber patch cable: Model FP63P, High NA Plastic Optical Fiber, NA 0.63
- Optical power emitted (typical maximum): 140 mW
- SMA905 connector (FC option upon request)
APPLICATIONS
- Fluorescence excitation of FITC, CY2, Alexa Fluor 488, Fluorescein
