What is a Spectroradiometer?

A spectroradiance meter (spectral radiance meter) is a machine that measures the radiance of light emitted from a light source separately for each wavelength. Generally, two sets of light have different radiances (spectral radiances) for each wavelength, even if they look the same color to humans. With two sets of light sources with different spectral radiances, one set of objects will look the same when illuminated, but another set of objects will look different. To prevent this phenomenon, it is essential to measure the spectral radiance using a spectroradiometer.
