Mastering Microscope Techniques for Clear Specimen Observation

This video tutorial demonstrates how to properly focus a microscope. It begins with setting up the microscope and adjusting the light intensity. The process of focusing at low power (10x) is explained, followed by focusing at medium power (40x) using fine focus. The video then covers the oil immersion technique for high power (100x) magnification. Finally, it concludes with instructions on cleaning and storing the microscope.

What is the first step in focusing a microscope?

• Adjusting the light intensity

• Turning on the microscope

• Placing the slide on the stage

• Using the fine focus knob

How should you adjust the light intensity when starting to focus?

• Set it to maximum

• Turn it off

• Adjust to about five or six

• Set it to minimum

What should you do if the specimen does not move when you wiggle the stage?

• Adjust the condenser

• Increase the light intensity

• Refocus on the correct plane

• Use the fine focus knob

When using the 40x objective, which focus adjustment should you use?

• Course focus

• Stage adjustment

• Fine focus

• Light intensity

What is the purpose of adding immersion oil when using the 100x objective?

• To protect the lens

• To clean the slide

• To improve resolution

• To increase magnification

What should you do after finishing your observations with the microscope?

• Leave the slide on the stage

• Turn off the light

• Clean the microscope and store it

• Rotate the 100x objective back into place
