| titleOfInvention | Optical filter and optical apparatus |
| abstract | An optical filter and an optical instrument having stable optical characteristics with a film configuration that has a sharp rise in spectral characteristics at the boundary between a stop band and a transmission band, suppresses ripples in the transmission band, and is easy to control during film formation. I will provide a. A low-refractive index layer 20 and a high-refractive index layer 21 are alternately stacked, and a first stacked portion 22 in which a refractive index of the high-refractive index layer 21 gradually increases toward a substrate 18 is provided. A second laminated portion 23 adjacent to the laminated portion 22 and having a refractive index of the high refractive index layer 21 substantially the same as the highest refractive index of the high refractive index layers 21 constituting the first laminated portion 22; A third laminated portion 24 adjacent to the second laminated portion 23 and having a refractive index of the high refractive index layer 21 that gradually decreases from the second laminated portion 23 side. The first to third laminated portions 22 The refractive index of the low refractive index layer 20 constituting ˜24 is substantially the same, and the absolute value of the refractive index gradient of the high refractive index layer 21 constituting the first laminated portion 22 and the third laminated portion 24 is different. It is supposed to be configured. [Selection] Figure 5 |
