Which part of a compound light microscope is primarily responsible for focusing light onto the specimen?
A
Eyepiece (ocular lens)
B
Stage
C
Objective lens
D
Condenser
Verified step by step guidance1
Understand the function of each part of the compound light microscope: The eyepiece (ocular lens) magnifies the image, the stage holds the specimen, the objective lens provides primary magnification, and the condenser focuses light onto the specimen.
Recall that the condenser is located beneath the stage and is specifically designed to gather and focus light from the microscope's light source onto the specimen.
Eliminate incorrect options: The eyepiece and objective lens are involved in magnification, not focusing light. The stage is a platform for holding the specimen and does not interact with light.
Identify the correct answer based on the function of the condenser, which is to direct and concentrate light onto the specimen for better visualization.
Conclude that the condenser is the part of the microscope primarily responsible for focusing light onto the specimen.
