Abstract
Cover glasses and mounting medium together constitute the de facto front lens of every microscope objective. Even though flat, and not curved as lenses are, their combined thickness and optical properties influence the quality of image formation by objectives and eyepieces. Those who coverslip are, in effect, completing the assembly of a microscope objective with every cover glass they apply. So while coverslipping is a tedious process, its visibly appreciable contribution should not be overlooked.
