Abstract:
A light measuring arrangement maintains the initial filtering function of an optical filter having a dye dispersed therein. The light measuring arrangement includes a measuring unit configured to measure an intensity of light emitted from a measurement target at a predetermined wavelength. The light measuring arrangement also includes the optical filter unit having the dye. The light measuring arrangement also includes a dye diffusion restricting unit configured to restrict diffusion of the dye from the optical filter unit. The optical filter unit constitutes part of an optical path for the light traveling from the measurement target to the light measuring unit.
