Lithium Niobate wafer for optical Low-pass filter and Isolator applictions |
LN has a characteristic of large birefringence. Birefringence is the difference between the normal ray refractive index and extraordinary ray refractive index.Since LN has a birefringence of 10 times greater than quartz and allows a low-pass filter to be thinly built, it is used in top class Digital S.L.R.(single-lens refles) Cameras. LN wedge chips usally areUsed for optical polarizer inside isolator,Insteading of YVO4 beacause its lower cost. |
