How it works

A microscope eyepiece, also called an ocular, is the lens assembly the user looks through to view the microscope image.

Eyepiece magnification, field of view, and compatibility affect total magnification and user viewing comfort.

Technical guide
Widefield eyepiece

A widefield eyepiece is designed to provide a wider viewing field than basic eyepiece designs.

A wider field helps users inspect more of the sample area without moving the stage as much.
