Review for optical (THE PETROGRAPHIC MICROSCOPE)

1.) What component of the microscope accommodates the lamphouse, containing a 50-100W high-energy tungsten-halogen lamp?

• Illuminator

• • Base

• Switch

• • Transformer

2.) Which part of the microscope is a steady light source often used for transmitted light microscopy?

• Potentiometer

• Transformer

• Illuminator

• Filter

3.) What is the function of a switch in a microscope?

• Adjust LED brightness

• Measure displacement

• Turn the illuminator on

• Control illumination intensity

4.) What does a transformer do in a microscope circuit?

• Trades voltage for current

• Controls illumination intensity

• Measures displacement

• Cuts down light reaching the sample

5.) Which component is used to measure displacement in any direction?

• Illumination intensity

• Potentiometer

• Condenser

• Diaphragm/aperture

6.) What is the purpose of illumination intensity adjustment in a microscope?

• To control illumination color

• To dynamically adjust LED brightness

• To restrict light passing through the sample

• To focus the illuminator light onto the sample

7.) Which component is often added to compensate for the odd color of the light, providing a truer white light to pass through the sample?

8.) What parts of the microscope are located above the base but below the stage?

9.) What component of the microscope cuts down the amount of light that reaches the sample by restricting the area that light can pass through?

• Condenser

• • Transformer

• Diaphragm/aperture

• Illuminator

10.) What is the function of a condenser in a microscope?

• To adjust LED brightness

• To measure displacement

• To control illumination intensity
