MCQ on Principles of Confocal Microscope with Answers for Students and Exams

A confocal microscope is an advanced optical microscope that uses laser light to scan specimens point by point. It employs a pinhole aperture to block out-of-focus light, producing clearer and sharper images. This technique allows for optical sectioning, enabling 3D reconstruction of samples. Confocal microscopes are widely used in cell biology, neuroscience, and medical research for detailed imaging. This is an MCQ on Principles of Confocal Microscope and Cone Focal Microscopy with answers.
