Microscope Eyepiece

The microscope eyepiece is the optical lens where we see the final image of specimen. These optics are sometimes referred to as 'ocular lenses' or 'oculars'. The eyepiece looks like a deceptively simple optical component of the microscope. The eyepiece is half of the optical system that lets you see the object with a magnified view. The other part is the objective. The combination of the eyepiece and the objective provides you with the total magnification. On each eyepiece, there is a number followed by an X. For example, 10X is the magnification of the eyepiece. The optical tube is the part of the microscope that holds the eyepiece. A compound microscope has one or more eyepieces that can be changed or swapped to other eyepieces, if they are compatible with the same tube diameter.
