|
|
monocular refers to..
|
that there is only one ocular lens
|
|
light refers to..

|
|
ocular lense always has a magnification of?
|
10X
|
|
3 objective lenses
|
scanning: gives a 4X mag, gives the broadest view (big pic but not as much detail) among all 3 lenses
low power: gives 10X mag
high power: gives 40X mag, gives the most detailed view
|
|
total magnification
|
maginification of Ocular Lens(is always 10X) multiplied by magnification of Objective Lens (depends on which objective lens in use)
