Sidewall … WebColored Glass Filters and other absorbing filters like Plastic Filters and Wratten Filters, introduce elements, compounds, dyes, or other colorants to a base substrate to manipulate the filter’s spectral properties. The resulting filters are relatively inexpensive, but have less desirable optical properties than similar coated filters.

WebAs a consequence of the interference laws, the interference filter will pass the most light at integer multiples of λ/2 and will pass the least amount of light at odd integer multiples of λ/4. Interference filters are convenient when there is only one wavelength of interest. A common application of interference filters is in inexpensive optical WebA Bragg tunable filter is a filter that exploits Bragg gratings in order to extract a small bandwidth of wavelengths out of a polychromatic input. As stated by Bragg’s law, θ determines which wavelength is diffracted. Hence, by tuning the angle of the grating, it is possible to scan the output wavelength over hundreds of nanometers.
