• Turn the light source off and on again.

• Check that the hair is centered in the field of view.

• Adjust the diaphragm to lower the light level.

Match the part of the microscope to its function-

Diaphragm

• magnifies 10x and is included when calculating total magnification

• used to focus on a specimen when in low power

• used to focus on a specimen when on high power

• changes the amount of light entering the microscope
