EyepieceClose Λ

Eyepiece is also called ocular.
Eyepiece is a visual optical device that is used to observe an image formed by an objective lens after magnification.
Eyepiece can magnify the real image obtained by the magnification of the objective lens to form a clear and erect virtual image at the least distance of distinct vision (LDDV). For aberration, eyepiece is usually composed of several lenses that correct the residual aberrations produced during imaging by the objective lens. Usually, eyepiece has a relatively larger field of view and angular magnification.

The eyepiece is provided with a diaphragm in the middle of the upper and lower lenses, or at the lower end of the lower lens, wherein micrometer, reticle, pointer and other accessories are mounted.
On the eyepiece there is engraved with the following marks: eyepiece type, magnification, field of view number, and the like. For example, eyepiece is engraved with PL10X/22; PL represents plane eyepiece, or flat-field eyepiece, 10X is the magnification, 22 represents the field of view, and the glasses mark represents high eyepoint eyepiece, and C represents compensating eyepiece.
Generally, the outer diameter of the eyepiece of a compound microscope is 23.2 mm, and stereo microscope can have a much larger field of view diameter because of its low magnification, so the outer diameter is mostly 30 mm (or 30.5 mm).

The resolution capability of the microscope is determined by the numerical aperture of the objective lens, while the eyepiece plays only the magnification role. Therefore, for structures and details that cannot be distinguished by the objective lens, the eyepiece still cannot distinguish even if it is magnified again.

Eyepiece Optical MagnificationClose Λ

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 250 mm/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.

Eyepiece Field of ViewClose Λ

The eyepiece field of view is the diameter of the field diaphragm of the eyepiece, or the diameter of the image plane of the field diaphragm imaged by the field diaphragm.
The diameter of a large field of view can increase the viewing range, and see more detail in the field of view. However, if the field of view is too large, the spherical aberration and distortion around the eyepiece will increase, and the stray light around the field of view will affect the imaging effect.

Eyepoint TypeClose Λ

Eye point refers to the axial distance between the upper end of the metal frame of the eyepiece and the exit of pupil.
The exit of pupil distance of high eyepoint eyepiece is farther than that of the eye lens of the ordinary eyepiece. When this distance is greater than or equal to 18mm, it is a high eyepoint eyepiece. When observing, one does not need to be too close to the eyepiece lens, making it comfort to observe, and it can also be viewed with glasses. Generally, there is a glasses logo on the eyepiece, indicating that it is a high eyepoint eyepiece.

PackagingClose Λ

After unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions. In order to save space and ensure safety of components, some components will be placed outside the inner packaging box, so be careful of their inspection.
For special packaging, it is generally after opening the box, all packaging boxes, protective foam, plastic bags should be kept for a period of time. If there is a problem during the return period, you can return or exchange the original. After the return period (usually 10-30 days, according to the manufacturer’s Instruction of Terms of Service), these packaging boxes may be disposed of if there is no problem.
