Depth of focus microscope definition
Webdepth of focus: the range of distances of the image behind a camera lens or other image-forming device measured along the axis of the device throughout which the image has acceptable sharpness. WebDepth-of-Field. When observing an object with a lens, the object is most clearly viewed when it is at the focal point of the lens. If the distance between the lens and the object is slightly varied, then there is a range …

WebTo focus a distant object (s 1 ≈ ∞), the rear principal plane of the lens must be located a distance s 2 = 50 mm from the film plane, so that it is at location of the image plane. To focus an object 1 m away (s 1 s 2 = 52.6 mm. The focal length of a lens determines the magnification at which it images distant objects.

The ability to correct the aberrations of the probe-forming lens in the scanning transmission electron microscope provides not only a significant improvement in transverse resolution but in addition brings depth resolution at the nanometer scale. Aberration correction therefore opens up the possibility of 3D imaging by optical sectioning. gerald montgomery facebook
