Spectroradiometric Luminance Meter

A spectroradiometer disperses light into a spectrum using a prism or grating and measures the radiance at each wavelength with a detector. It is used to detect the luminous properties of light sources, displays, and materials, with applications in lighting quality inspection, screen calibration, and color analysis.
Selection
When selecting, consider the measurement wavelength range and accuracy to match the characteristics of the object being measured. Pay attention to the instrument's resolution and response speed to adapt to different measurement scenarios. Check the calibration certificate and probe compatibility to ensure long-term measurement stability. Evaluate the operation interface and data output formats to meet practical usage needs.
