Abstract
Excitation light is inputted to an optical element with uniformly dispersed inorganic fluorescent nanoparticles whose radius is controlled. Fluorescence is emitted from the inorganic fluorescent nanoparticles through photoexcitation and outputted from one end of the optical element. By controlling the radius of the inorganic fluorescent nanoparticles dispersed in the optical element, the wavelength range and spectral width of the light outputted from the optical element are controlled.
Claims12
An optical measuring apparatus for measuring characteristics of a test section using light emitted from a light source, wherein the light source comprises:
- an optical element with multitudes of inorganic fluorescent nanoparticles dispersed therein, the fluorescence energy level of the nanoparticles being controllable by the diameter thereof;
- and
- an excitation light source for emitting excitation light with a wavelength in the wavelength range capable of photoexciting the fluorescence energy level of the inorganic fluorescent nanopaticles.
