If the ocular magnifies 15X & the objective lens magnifies 20X, what is the total
magnification of the lens system? - Answer -300x
(multiply the two numbers)
What is the total magnification of YOUR microscope at LOW power? - Answer -100x
SCAN:
-Magnification: 40x
-Field view of diameter: 5000um
LOW:
-Magnification: 100x
-Field view of diameter: 2000um
HIGH:
-Magnification: 400x
-Field view of diameter: 500um
ULTRA HIGH:
-Magnification: 1000x
-Field view of diameter: 200um - Answer -when calculating how many LONG a cell is:
divide FOVD by # of cells
FVOD/# of cells = ...um
ex: 2000um/5 cells = 400um
If your WORKING DISTANCE is 11 millimeters at SCAN power, then
a) it is greater than 11 mm at LOW power
b) it is greater than 11 mm at HIGH power
c) it is less than 11 mm at LOW power
d) it is the same - Answer -c) it is less than 11 mm at LOW power
