Abstract: A Fabry-Perot interferometer includes an input mirror and an output mirror arranged facing the input mirror via a gap. Each mirror includes a pair of high-refractive layers and a space layer arranged selectively between the high-refractive layers. At least one of an input-side bridge part and an output-side bridge part arranged crossing the gap, is movable as a membrane. Each bridge part includes a transmission portion and a periphery portion. Each transmission portions includes a mirror element in which the space layer is sandwiched by the pair of high-refractive layers. In a second direction perpendicular to the first direction, the mirror element of the input mirror has a width larger than seven times of a maximum wavelength of a transmission light output from the output mirror, and functions as a diffraction restriction mirror.

Abstract: An optical component for reflecting incident light at a predetermined reflection angle, includes: a scan portion having a reflection surface and scanning the reflection angle; and a package accommodating the scan portion, and having a main body of a box shape with one open surface and a lid which covers the one open surface and transmits the incident light and reflected light. The lid includes at least one base portion having a counter surface facing the reflection surface and a back surface opposed to the counter surface, and a diffraction lens portion arranged on at least one of the counter surface and the back surface and having a periodic concavo-convex shape so as to widen the reflection angle.

Abstract: A liquid component sensor includes: an infrared light source; a detection cell including: two substrates made of material for penetrating an infrared light therethrough and stacked each other; a passage for flowing liquid arranged between facing surfaces of the substrates; and a detection portion for detecting the liquid provided by at least a part of the passage; a spectrometer for dispersing light penetrating the detection cell; and a light detector for detecting dispersed light. Each substrate includes outside and facing surfaces, so that two substrates provide four surfaces totally. The detection cell further includes a filter for passing the infrared light having a predetermined wavelength selectively. The filter is disposed on at least one of four surfaces at a predetermined position, which corresponds to at least the detection portion.

Abstract: A lens reflecting a light of a predetermined wavelength, or transmitting and condensing or diverging the light is provided. The lens includes a substrate, and a quasi-periodic structure layer. A plane of the quasi-periodic structure layer is divided into unit cells and is filled with the unit cells in a two-dimensional period. The unit cell has a first region and a second region. An occupancy rate is changed as a distance from a center of the substrate. A resonance mode is defined by a relationship between the occupancy rate and the period length. A lowest order resonance mode is defined by the resonance mode. The period length is set to a predetermined value within a predetermined range including an optimum value. Another lens is provided. A minimum occupancy rate is defined by a smallest occupancy rate. A variation range of the occupancy rate changes across the minimum occupancy rate.
