Magnification is inversely proportional to the diameter of the field of view.
i think that you do math?
It is +4x
4x * x = 4x^2
The lens with the smallest magnification has the largest field of view.( usually 4x)
five
If the entire field of view is 32 mm and the object occupies 25% of that then you will multiply 32 by 0.25. The result is 8 mm.
0.6 mm
0.56 mm. because total field of view on medium power is 1.7 mm. divide this with 3 and you get 0.56.
yes.
it will increase the magnification of the image of specimen
It depends on the actual focal length. For a 35 mm format lens, 200 mm is about 4x magnification, to get 20x you'd need a 1000 mm lens. For smaller formats, such as 8 mm or a camcorder, find the focal length for normal view, then multiply by 20.
100x the higher the magnification the shorter the working distance
40x is magnified more, so if you zoom in on something, you're only seeing a part of what it was before. Versus, if you zoom out, you see more. It's not as detailed, but it's a larger field of view.
1,600 (micrometers {microns} per one field of view) divided by 40 (cells per field of view) equals [units cancel] 40 microns per cell.
18 mm is the wide angle focal length and 200 mm is the telephoto limit of the zoom. for more info searching on focal length and field of view will give you lots of info.
