Although the two lamp families (Calibrated Irradiance Sources and Spectral Calibration Lamps) have decidedly separate purposes, they are often used together to completely calibrate a system. To achieve the highest accuracy, we suggest you use a spectral line lamp for wavelength calibration, then a calibrated irradiance lamp with a stabilized, radiometric power supply for power level calibration. Use the calibrated deuterium source for the 200 to 400 nm range, and a calibrated quartz tungsten halogen source for the 250 to 2400 nm range. If utmost accuracy is not crucial, our Hg(Ar) spectral calibration lamps may be used for spectral calibration and to determine relative power level calibration.
