QE is a ratio as described by your Wikipedia link. There is a massive difference between a ratio of 0.5 and 1.0!
- nayuki 3y ago0.5 to 1.0 is just one F-stop in photography. If you make your sensor 2× better, that's not going to overcome a 100× reduction in front glass area when moving from a DSLR to a phone.
- yunohn 3y agoNo, I’m saying you have completely misunderstood QE. 1 is the upper limit - 100% efficiency. You can’t just say 50% is very close to 100%!
