Verified step by step guidance

1. Understand the basic components of a bright-field microscope: the light source, condenser, stage, objective lens, and eyepiece.
2. Recall that the condenser is located below the stage and its primary function is to gather and focus light onto the specimen to illuminate it evenly.
3. Recognize that the objective lens is responsible for magnifying the image of the specimen after it has been illuminated.
4. Know that the eyepiece further magnifies the image formed by the objective lens for viewing by the observer.
5. Identify that the stage is the platform where the specimen slide is placed, but it does not focus light.
