Highest focal length lens
WebThe focal length of a lens is the optical distance (usually measured in mm) from the point where the light meets inside the lens to the camera’s sensor. “You can zoom in on your phone, but that’s not changing your focal length. That’s just cropping your photo before you actually take it,” photographer Derek Boyd points out.

WebSome lenses are used for focusing collimated laser beams to small spots. The numerical aperture of such a lens depends on its aperture and focal length, just as for the collimation lens discussed above. The beam radius w lens at the lens must be small enough to avoid truncation or excessive spherical aberrations.
