Microscopy

Microscopic anatomy

Unsee to the human eye. Studies the structures of cells(cytology), tissues (histology), and organs.

Compound microscope

Through the use of 2 lenses, this precision instrument is used in laboratories to view histology slides and wet mounts

Magnification

To make something larger

resolution

The ability to see two items as separate and discrete units rather than a fuzzy, overlapped single image

contrast

How well an image can be seen against its background

Brightness

The lightness or darkness of the field of view

field of view

The area you can see through the microscope

Parfocal

idea that the slide should be in focus (or nearly so) at a higher magnification once you have properly focused without touching the focusing knobs

Depth of field

The thickness of the specimen that is in complete focus. Depth will be greater in lower magnifications. The higher the magnification, the lower the lower the depths.

Working distance

How far the object lens is from the specimen

4x

scanning lens

10x

lower-power lens

40x

High-power lens

100x

oil immersion lens

Total magnification

Ocular lens x objective lens
