Web14 de out. de 2024 · We didn’t think the higher number was really necessary, and honestly, we weren’t sure that any of our lenses would adequately resolve even 200 lp/mm. This time, though, we felt comfortable we could test at 240 lp, and doing that, let us also test at 192 lp/mm, which is pretty close to the original 200 lp peak. WebThe limiting resolution of a camera with 100μm pixels. = 1000μm/mm ÷ 2 x Pixel Size (in μm) = 500/Pixel Size (in μm) = 500/100 = 5lp/mm. Per Nyquist, it takes a minimum of two pixels to resolve a feature in an image. The highest spatial frequency which can be resolved by a sensor, the Nyquist frequency, is effectively two pixels or one ...
Focal Length: An Easy Guide to Using and Understanding Camera Lenses

Microscope objective lenses will often have four numbers engraved on the barrel in a 2x2 array. The upper left number is the magnification factor of the objective. For example, 4x, 10x, 40x, and 100x. The upper right number is the numerical aperture of the objective. For example 0.1, 0.25, 0.65, and 1.25. small vector images
