ANSI/IES LM-58 Spectroradiometric Measurement Methods for Light Sources

This document describes the requirements and recommendations of the instruments and procedures for spectroradiometric measurements, including those of color performance, spectral irradiance, spectral radiance, and spectral total radiant flux, either in relative or absolute units. The spectral range is from approximately 200 nm to 1,700 nm, where the characterization of light from light sources, visual displays, and light emitting diodes is most commonly done.

LISUN following instruments fully meet ANSI/IES LM-58 Spectroradiometric Measurement Methods for Light Sources:

LMS-7000 CCD Spectroradiometer

LMS-9000C High Precision CCD Spectroradiometer

LMS-9500C Scientific Grade CCD Spectroradiometer
