Question

Quizplus · Accepted Answer

A parfocal microscope is one that can maintain focus when changing between magnifications, allowing for seamless observation and analysis without having to refocus the specimen. This is achieved through the use of specialized lenses and adjustments within the microscope, making it a valuable tool for many different applications. While parfocal microscopes may also have other features like multiple sources of illumination and fine focusing adjustments, the ability to stay in focus between magnifications is the defining characteristic.
