  • Optical structure to reduce internal reflections
    Patent number: 8252390
    Abstract: A structure for reducing internal reflections in an optical system includes a stack of layers including a first layer having a first refractive index, a second layer having a second refractive index, a third layer having a third refractive index, a fourth layer having a fourth refractive index, and a fifth layer having a fifth refractive index. The second layer is arranged between the first layer and the third layer, and the fourth layer is arranged between the third layer and fifth layer. Further, the third refractive index is greater than the second and fourth refractive indexes, the second refractive index is greater than the first refractive index, and the fourth refractive index is greater than the fifth refractive index.
