The optical magnification of eyepiece

Eyepiece optical magnification is the visual magnification of the virtual image after initial imaging through the eyepiece. When the human eye observes through the eyepiece, the ratio of the tangent of the angle of view of the image and the tangent of the angle of view of the human eye when viewing or observing the object directly at the reference viewing distance is usually calculated according to 250mm/focal length of eyepiece.
The standard configuration of a general microscope is a 10X eyepiece.
Usually, the magnification of the eyepiece of compound microscope is 5X 8X 10X 12.5X 16X 20X
As stereo microscope has a low total magnification, its eyepiece magnification generally does not use 5X, but can achieve 25X 30X and other much bigger magnification.
