The object of the present invention is to provide a holographic notch filter which can favorably reject and remove a narrow, desired range of wavelengths of the incident light and a method of easily manufacturing the holographic notch filter. For achievement of the above object of the present invention, a multi-structure holographic notch filter 2 having a holographic recording material 4 arranged on which modulations of the refractive index are recorded by two-beam interference is provided as characterized in that a thin-film filter element 6 is fabricated from a thin form of the holographic recording material 4 in which modulations of the refractive index are recorded by the two-beam interference and a plurality of the thin-film filter elements 6 are joined together to develop a layer arrangement.
A multi-structure holographic notch filter having a holographic recording material arranged on which modulations of the refractive index are recorded by two-beam interference, characterized in that:
A method of manufacturing a multi-structure holographic notch filter having a holographic recording material arranged on which modulations of the refractive index are recorded by two-beam interference, comprising the steps of:
