Abstract
A tunable filter is described for microscopic Raman imaging. The filte r employes two matched-volume holographic transmission gratings in a d ispersion/dedispersion configuration and is useful throughout the visi ble wavelength region. Average transmission is greater than 75%. The f ilter performance is demonstrated with brightfield images of a bar tar get, Raman images of a silicon integrated circuit, and brightfield ima ges of mineral inclusions in glass.
