最近買了KENKO Pro 1D的CPL，
聽老闆說它有獨特的Wideband是別人沒有的，
在產品的外觀上也有寫，
但是對於Wideband這個特點，
不知道有沒有神人可以分享一下心得?!

希望有神人可以幫我解惑一下
原文是
The transmission curve and the coefficient of extinction are identical to the twin model. Flares, mean transmission, scattering and vignetting likewise. C1 and C2 graphs are different than competition’s products. Their shape is preserved, it’s angles of inclination that changed. It’s possible that the phase retardation is slightly bigger or the quarter-wave plate has a flattened dispersion. In such case the polarizer would be circular in a wider spectrum and that would explain the “wide band” in its name. If that’s the truth (and everything points at it) then it deserves praise. Kenko was also better at homogeneity test. This suggests that Hoya uses cheaper and less homogeneous quarter-wave plates. This caused that Kenko is 3 places higher than Hoya.
