microscopy

Question 1

what is used to magnify and see specimens what the naked eye cannot see

Answer 1

microscope

Question 2

who discovered the microscope

Answer 2

ZACHARIAS JANSSEN

Question 3

who is the father of the microscope?

Answer 3

ANTONI VAN LEEUWENHOEK

Question 4

microscope with one lens, Similar to this will be a Magnifying lens but we don’t call this a microscope because it is only a lens

Answer 4

SIMPLE MICROSCOPE

Question 5

two or more lens,

Answer 5

COMPOUND LIGHT MICROSCOPE

Question 6

• Has space for your hands to move
• It doesn’t have a stage
• light source at the top and bottom

Answer 6

STEREOMICROSCOPE

Question 7

what allows u to see whatever is in here and to see whatever is in focus thus allowing you to trace viewed specimens

Answer 7

drawing tube

Question 8

microscope that is only used by experts and depends on electron beams to show you images

Answer 8

electron microscopy

Question 9

allows you to view the surface

Answer 9

sem image or scanning electron microscope

Question 10

shows you which structure of the specimen is more dense than the other, allows u to differentiate or identify the different parts or the internal structures of the specimen

Answer 10

tem image or transmission electron microscope

Question 11

this is the real 3d, allows u to view surface and internal structures

Answer 11

atomic force microscopy

Question 12

similar to SEM image but instead of electron, it used laser. When you target a certain structure, you could select a certain die, subject it to the specimen, and view it under this microscope

Answer 12

confocal microscopy

Question 13

it is where u view the specimen and is 10x

Answer 13

eyepiece

Question 14

has a scanner that is 4x, LPO, HPO, AND OIO

Answer 14

Objective lenses

Question 15

Low power objective =

Answer 15

10x

Question 16

high power objective =

Answer 16

40x

Question 17

oil immersion objective =

Answer 17

100 x

Question 18

it can revolve or rotate and lets u view the specimen in diff. magnification

Answer 18

nose piece

Question 19

this is used when there are different or multiple lenses

Answer 19

total magnification

Question 20

how do u get the total magnification?

Answer 20

eyepiece mag. x objective mag.

Question 21

Where the specimen is placed
where the unknown length is

Answer 21

stage

Question 22

keeps specimen in place

Answer 22

stage clips/holder

Question 23

connects the eyepiece and nose piece

Answer 23

arm

Question 24

supports the whole microscope

Answer 24

base

Question 25

elevates and lifts, moves the stage, is bigger than other knob

Answer 25

coarse adjustment knob

Question 26

makes u zoom in and out, is the smaller knob

Answer 26

fine adjustment knob

Question 27

can reflect and gives u light. Makes the light pass through the condenser

Answer 27

light source / mirror

Question 28

it condenses light and make it much more brighter
- When you have higher magnification, the light should be much more focused.

Answer 28

condenser

Question 29

the bg is bright or white

Answer 29

white filmthe

Question 30

the bg is dark

Answer 30

black film

Question 31

we see this in electron microscope because it shows u which is much more darker

Answer 31

face contrast

Question 32

-placed directly on the eyepiece
-Known value, needs calibration
- it will look the same for all magnification

Answer 32

ocular micrometer

Question 33

placed on the stage

-Larger magnification = decrease in spaces
-Smaller magnification = increase in spaces
-can be magnified depending on the objective lens

Answer 33

stage micrometer

Question 34

computation of calibration factor

Answer 34

CF = (Sm) (10m) / (0m)

Question 35

computing for actual size

Answer 35

(0m)(CF)

Question 36

actual size ocular

Answer 36

number of spaces X CF
