Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

Filter is an optical device that can selectively pass through or block specific wavelengths of light, and is widely used in various fields according to its specific optical characteristics. The ...

Splitting white light into its constituent spectral components has been of interest ever since Newton first discovered the phenomenon of color separation. Many devices have since been conceived to ...
