  • OPTICAL COMPONENT
    Publication number: 20150116832
    Abstract: An optical component includes an optical substrate and a first band-pass filter disposed on the optical substrate. The first band-pass filter includes a high refractive index layer having a first refractive index, and a low refractive index layer having a second refractive index lower than the first refractive index. The high refractive index layer and the low refractive index layer are layered. An expression (nL×dL)/(nH×dH)?0.50 (1) is fulfilled, wherein the first refractive index is nH, the second refractive index is nL, the high refractive index layer has a physical film thickness of dH, and the low refractive index layer has a physical film thickness of dL.
