  1. Optical Beacon Wavelength Measurement (D. Real, F Urbano, A Sánchez, J Ruiz-Rivas) The three wavelength sources (LED @ 470 nm, and 400 nm and Laser) have been measured with a high res calibrated spectrometer from Ocean Optics HR4000CG-UV-NIR • Measurements: • A sample of 20 cleaved blue LEDs (Agilent HLMP-CB15) • Usual standard LED of LOB Beacons • Nominal wavelength: 472 nm (35 nm FWHM) • A sample of 15 cleaved HUVL 400-520 B • LED used in L12F2 and L11F2 • Nominal wavelength: 400 nm (20 nm FWHM) Spectrometer checked with the Green Nd-YAG Laser (532 nm)
