Which of the following would DECREASE the resolution of a histological image?
Show answer and explanation
Correct answer: Closing the condenser diaphragm excessively
Closing the condenser diaphragm reduces the cone of light entering the objective, which effectively lowers the Numerical Aperture of the system. While it increases contrast, it degrades the resolution.
