Title: LAMINATE BODY, OPTICAL SENSOR, AND KIT
Abstract:
This laminate body comprises at least one first reflective layer formed by immobilizing a liquid crystal phase in which the rotational direction of the helical axis is to the right and at least one second reflective layer formed by immobilizing a liquid crystal phase in which the rotational direction of the helical axis is to the left. In the 300-3000nm wavelength region, there is a first transmission band, the half value width in the first transmission band is 200nm or less, and the average transmittance in the wavelength region from the half value wavelength A on the short wavelength side of the first transmission band to the half value wavelength B on the long wavelength side thereof is 50% or greater. The average transmittance in the wavelength region from the half value wavelength A on the short wavelength side 100nm to the short wavelength side and the average transmittance in the wavelength region from the half value wavelength B on the long wavelength side 100nm to the long wavelength side are each less than 20%. The optical sensor includes the aforementioned laminate body, and the kit is used for manufacturing said laminate body.
