The iris of the optical microscope is:
A
the lens responsible for magnifying the image
B
the knob used to focus the image
C
a device that regulates the amount of light passing through the specimen
D

검증된 단계별 안내1
Understand the function of each part of the optical microscope mentioned in the options.
Recall that the lens responsible for magnifying the image is called the objective lens or the ocular lens, not the iris.
Recognize that the knob used to focus the image is called the focus knob (coarse or fine adjustment), not the iris.
Identify that the platform where the specimen is placed is called the stage, which is different from the iris.
Conclude that the iris is a device that regulates the amount of light passing through the specimen, controlling illumination and contrast.
