Bandpass filters
The use of bandpass filters is one of the simplest and most economical ways to transmit a welldefined band of light and to reject all other unwanted radiation. Their design is essentially a thin film FabryPerot interferometer formed by vacuum deposition, and consists of two reflecting stacks separated by an even-order spacer layer.
Because the Fabry-Perot filter is Lorentzian in shape, the cut-on ...

The use of bandpass filters is one of the simplest and most economical ways to transmit a welldefined band of light and to reject all other unwanted radiation. Their design is essentially a thin film FabryPerot interferometer formed by vacuum deposition, and consists of two reflecting stacks separated by an even-order spacer layer.
Because the Fabry-Perot filter is Lorentzian in shape, the cut-on and cut-off slopes are shallow and the rate of attenuation in the out-of-band blocking range is slow. To improve the slopes and increase the attenuation in the blocking band, we introduce more cavities into the construction of our standard dielectric bandpass filters
