1

Ocular lens

eyepiece / magnifies the image 10X

2

Objective lens

further magnifies the image

3

moves the body tube up and down in large increments to allow gross positionin and focusing.

11

ability to distinguish two objects as separate entities.

15

Fine & Coarse focus knobs are responsible for allowing the _____ of a specimen.

resolution

16

The ocular and objective lenses are responsible for the ______ of a specimen.

magnification

17

What is the magnification of the Ocular Lens?

10X

18

What is magnification of the following objective lenses?

  1. Scanning
  2. Low Power
  3. High Power (dry)

  1. Scanning--------4X
  2. Low Power -----10X
  3. High Power (dry-40X

19

Because you use both the ocular and objective lens, the specimen is magnified twice.

Calculate the Total Magnification when the Objective lens is the following:

Low Power.

Ocular lens x Objective lens = Total Magnification

Low Power.    10X x 10X = 100X

20

Because you use both the ocular and objective lens, the specimen is magnified twice.

Calculate the Total Magnification when the Objective lens is the following:

High Power (dry).

Ocular lens x Objective lens = Total Magnification

High Power (dry).    10X x 40X = 400X

21

Because you use both the ocular and objective lens, the specimen is magnified twice.

Calculate the Total Magnification when the Objective lens is the following:

Scanning.

Ocular lens x Objective lens = Total Magnification

Scanning.    10X x 4X = 40X

22

What is the calculation for total magnification?

Total magnification = Magnifcation of Ocular lens x Magnification of Objective lens
