LP/MM and can go up to over 200 LP/MM For example, a lens with resolution of 60 LP/MM on a 1/3-inch 1 3MP camera that has resolution of 133 LP/MM does not utilize the full resolution of the camera That's because the lens resolves only 60 LP/MM while the camera requires 133 LP/MM for its full megapixel resolution The lens cannot see enough

Limits of Resolution 3 Diffraction and Photosite Size
Resolution limits (lp/mm) for a perfect lens as a function of aperture and sensor photosite size are determined by simulation Results are shown for 20, 50, and 80 line-pair contrast ratios Smaller photosites always increase resolution and contrast (within the range of sizes and aperture values simulated), although marginal gains are small if diffraction blur is appreciably larger than
