Q:The ideal waverlength for us is 465 nm, can you offer?.
A:It is no problem, but you should know the wavelength should be a range, what we will offer you 465+/-2nm.

Q We actually want to check our reflectance (mirror type) measurement method on an LED structure on a PSS wafer. Would it be possible to get the same LED structure on both a PSS wafer and a single-side polished wafer so we can compare the two directly?
