WAVELENGTH CALIBRATION OF A SPHERE-SPECTROMETER MEASUREMENT CONFIGURATION (PO15, 483-484)

NMISA's LED measurement facility sphere-spectrometer measurement setup for total flux measurements was recalibrated to achieve lower uncertainties. The wavelength calibration was performed using a partial flux measurement configuration with the integrating sphere - array spectrometer system and pencil style wavelength sources. The calibration was performed on an optical bench to enable easy moving of lamps for better signal.
