The parts of the compound light microscope can be classified into 3 parts called ____________
Mechanical, Magnifying, Illuminating parts
The _______________ hold the different parts together and are used to adjust the magnifying parts and illuminating parts to focus a specimen.
Mechanical Parts
It is a device used to view objects too small to be seen with the naked eye
Microscope
Give the two magnifying parts of the compound microscope
Ocular lens/Eyepiece and Objective lens
Adjust the resolution of the HPO lens using the _____________.
Fine Adjustment Knob
Give at least 1 limitation of the compound microscope
Limited magnification power, Low resolution for very small structures, It requires thin amd transparent samples/specimen
What is formula in getting the total magnification power for the specimen.
TM = Eyepiece lens magnification x objective lens magnification
Give atleast 3 illuminating parts of the microscope
Condenser, Iris Diaphragm, Mirror, Light Source/ Illuminator
Give the 4 types of objective lenses
Scanner/ scanning object, LPO, HPO, OIO
It is used instead of the mirror in some microscopes
Light Source/ Illuminator
It reflects light and directs it to the object, then reflects the image back to the eyes
Mirror
It regulates how much light passes through the specimen and can be controlled using a lever
Iris Diaphragm
It concentrates light onto the specimen
Condenser
It is used to magnify the specimen under study
Objective lens
A detachable cylinder located on top of the draw tube that is used to view the specimen
Ocular lens/ Eyepiece
It provides firm and steady support to the entire microscope
Base
It provides support above the base and is where the arm is attached
Pillar
It attaches the arm to the pillar and used for tilting the microscope
Inclination Joint
It is used to to secure the specimen slide on the stage
Stage clips
This is the hole at the center of the stage for light to pass through the specimen
Stage Aperture
A flat platform where the specimen slide is placed
Stage
A circular and revolving part connected to the body tube that holds the objectives
Revolving Nosepiece
It supports the body tube and is used to carry the microscope
Arm
It moves the body tube upward or downward in lesser increments
Fine Adjustment Knob
It moves the body tube upward or downward in greater increments
Coarse Adjustment Knob
It connects the ocular lens to the revolving nosepiece
Body Tube
A small cylinder attached to the upper part of the body tube that holds the ocular lens
Draw Tube/ Eyepiece Tube
If the ocular lens has a magnification power of 5x and we use high power objective what will be its total magnification power?
200x
A type of objective lens with a magnification power of 100x
Oil Immersion Objective
A type of objective lens with a magnification power of 40x
High Power Objective
A type of objective lens with a magnification power of 10x
Low Power Objective
A type of objective lens with a magnification power of 4x
Scanner/ Scanning Objective
A compound microscope that has two ocular lenses is called _________
Binocular Microscope
A compound microscope that has only one ocular lens or eyepiece
Monocular Microscope
The most common microscope used in science laboratories is the ___________.
Compound Microscope
He is the father of microbiology
Antonie van Leeuwenhoek
They invented the compound microscope in the late 16th century
Hans and Zacharias Janssen
