Spectral Irradiance Meter

A spectroradiometer decomposes light into different wavelengths through a spectral system and measures the light intensity at each wavelength. It is used to detect the spectral distribution and illuminance values of light sources, monitor ink color rendering in the printing industry, evaluate material light resistance in the plastics industry, and measure lighting parameters in laboratories.
Selection
When selecting, consider that the measurement wavelength range should cover application needs, precision should match detection standards, and probe size should suit the measured object. Pay attention to the instrument's calibration cycle and temperature stability, ensure the operation interface aligns with user habits, and verify that data interfaces meet recording requirements.
