GENERAL HISTOLOGY

Detailed explanation-1: -Typically, a compound microscope is used for viewing samples at high magnification (40-1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).

Detailed explanation-2: -High Power Objective Lens (40x) The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample.

Detailed explanation-3: -Objective Lenses: The high-power objective lens is 40x. The oil immersion objective lens is usually the longest of the objective lenses and has a magnifying power of 100x.

Detailed explanation-4: -Field of view is how much of your specimen or object you will be able to see through the microscope. At 40x magnification you will be able to see 5mm. At 100x magnification you will be able to see 2mm. At 400x magnification you will be able to see 0.45mm, or 450 microns.

Detailed explanation-5: -To get the total magnification level you must multiply the magnification of the ocular lens by the magnification of the objective lens. So, if you are viewing your slide under the 40x objective lens you would multiply that by the 10x of the ocular lens for a total magnification of 400x.
