Use these standards for calibration and verification of spectroscopic instruments. Calibrate spectrometer using 99% reflectance standard. Verify linearity of spectrometer’s response as light intensity varies from 99% down to 2%. Verify color measurement precision over entire visible spectrum for machine vision and spectroscopy applications requiring precise color representation. The 99% reflectance standard, used frequently in calibration, is available separately or as part of four-standard set.
