Objective protector and microscope observation method

摘要

The present invention reduces or removes the need to clean an objective lens, thus simplifying the observation procedure, prevents bacteria or contamination from adhering to the objective lens, and protects the objective lens from external force that would be exerted during cleaning. The invention includes an optically transparent covering configured to cover at least an end surface of an objective lens; and an attaching mechanism configured to attach the covering to the objective lens.
