frozenblaze Posted November 23, 2007 Share Posted November 23, 2007 Searching on my Pt-AE2000E specs I noticed this ratio as 85%. Wondering what does it mean, and how does it effect the picture? Thanks Link to comment Share on other sites More sharing options...

Thanks I think it is brightness uniformity - the corners are 15% dimmer than the middle. It seems like a lot, but brightness perception is logarithmic, so this is measurable but not noticeable by most people. In camera lenses, it is focus and/or colour shift due to refraction. In telescopes, it is acuity (smallest resolvable object) Link to comment Share on other sites More sharing options...
