Understanding spectral irradiance and how to realize a stable, traceable scale

This book explains a practical method for determining spectral irradiance using tungsten-halogen lamps and radiance-to-irradiance transfer. It shows how to model drift, perform wavelength interpolation, and quantify uncertainties to produce a reliable irradiance scale.

The author outlines a step-by-step realization process, discusses how to handle lamp drift, and presents data-fitting techniques that connect measured radiance to spectral irradiance across a wide wavelength range. It also explains how to combine measurements, time-dependent corrections, and error sources to improve accuracy in spectroradiometric work.

• Learn the measurement scheme for comparing irradiance lamps and radiance sources
• See how drift modeling and least-squares fitting are used to generate spectral irradiance data
• Understand how uncertainties are estimated and combined for a robust scale
• Explore practical guidance on applying these methods to realize a spectral irradiance standard

Ideal for readers engaged in photometry, radiometry, standards, and laboratory measurement science seeking a rigorous, real-world method for spectral irradiance realization.
