+Diffraction Grating - What is it?

Light that reflects from a sample into the pickup optics (measurement optics) is a mixture of various wavelengths. Before spectral reflectance is measured, this light is divided into its individual spectral components. Mixed light that passes through the diffraction grating is transmitted as a spectrum (as if it had passed through a prism). The SpectroEye, Spectrolino, Eye-One Pro, iCColor, and iSis use this color measurement technology.

Diffraction Grating is also called monochromator.
