Verified step by step guidance1
Understand the main components of a compound light microscope and their functions.
Recall that the eyepiece (ocular lens) is used to magnify the image formed by the objective lens, not to focus light onto the specimen.
Recognize that the objective lens is responsible for magnifying the specimen itself, but it does not primarily focus light onto the specimen.
Identify that the stage is the platform where the specimen is placed, but it does not have a role in focusing light.
Conclude that the condenser is the component designed to focus and direct light from the light source onto the specimen, enhancing illumination and image clarity.
