WebbBandpass filters are one of the simplest and most economical ways to transmit a well-defined band of light and to reject all other unwanted radiation. Their design is essentially a thin film Fabry-Perot Interferometer formed by vacuum deposition techniques and consists of two reflecting stacks, separated by an even-order spacer layer. WebbLong pass filters, sometimes referred to as long pass edge filters, are designed to transmit wavelengths within a given wavelength range. This band is defined by the filter’s cut-on edge which essentially blocks frequencies shorter than the specified edge wavelength. Long pass filters typically have a steep cut-on with close to zero ...
