I'm curious if there is a cheap and simple method for measuring the transmissibility (or whatever the word is) of optics, such as my scope? Somewhat to verify manufacturer's claims, but mostly to compare my current scopes to each other and maybe other potential purchases.
I know this is not needed or very important, but I'm a science geek and this is something I've always wondered about. The only way I've thought of so far is to cover each scope with a blind that has the same sized hole in it, then expose it to the same light at the same distance, and measure the light once it's output on a solar cell or photosensor, but that doesn't sounds too accurate to me.
