Introduction to the Microscope Care Parts Focusing

Always carry with 2 hands Only use lens paper for cleaning Do not force knobs Always store covered

Keep objects clear of desk and cords Parts of a Compound Microscope compound microscope

Eyepiece Body Tube Revolving Nosepiece Objective Lens Stage Clips Diaphragm

Arm Stage Coarse Focus Fine Focus Light Base

Compound Microscope A microscope is a very powerful magnifying glass A microscope helps you see things like cells

up close Eyepiece View the specimen through the eyepiece

Stage Clips & Objectives Stage clips hold the slide in place Low power objective is used to focus the

microscope (short & fat) High power objective is used to view details of a specimen Coarse Adjustment,

Fine Adjustment, & Base Coarse adjustment focuses adjustment Fine adjustment fine tunes & gives detailed focus(usually smaller than coarse

adjustment knob) Base is where the microscope rests Stage Stage is part where the slide rests

Mirror (or light source) directs light upwards onto the slide. Diaphragm Diaphragm allows light in

Nosepiece Nosepiece is the rotating device that holds the objectives (lenses)

Arm Arm is the part where you carry the microscope

Can you name the parts of a compound microscope? Answers 1) base 2) mirror (light source) 3) diaphragm 4) stage

5) stage clips 6) low power objective lens 7) high power objective lens 8) nosepiece 9) arm 10) fine focus knob 11) body tube 12) coarse focus knob

13) eyepiece Types of Microscopes Light microscope (for small objects similar to the way binoculars magnify objects far away.)

The Compound Light Microscope http://www.cas.muohio.edu/~mbi-ws/microscopes/compoundscope.html May have many lenses that magnify the object

Eyepiece = 10x magnification Objective = 10x (low) or 40X (high) Total magnification= eyepiece X objective ex: 10x X 40x =

400x total magnification Compound Light Microscope Powered by Light & Lenses a) Powers of Magnification Ocular Lens= _________ Low Power Objective= _______

Medium Power Objective= _______ High Power Objective= _______ Calculating Total Magnification= ____________ b) Resolution c) Parts

Stereomicroscope To look at large things that light cannot pass through (one eyepiece for each eye) Stereomicroscopes http://scientificsonline.com/product.asp_Q_pn_E_3119600

http://www.martinmicroscope.com/MicroscopePages/Stereomicroscopes.htm Stereomicroscopes 3 - D image can only magnify 10x to 600x Electron Microscope

can magnify more than 500,000x House Fly http://www.pbrc.hawaii.edu/bemf/microangela/hfly.htm

Place the Slide on the Microscope Use Stage Clips Click Nosepiece to the lowest (shortest) setting Look into the Eyepiece Use the Coarse Focus

Follow steps to focus using low power Click the nosepiece to the longest objective

Do NOT use the Coarse Focusing Knob Use the Fine Focus Knob to bring the slide into focus What can you find on your slide?
