The magnification of the eyepiece is inversely proportional to its length, while the magnification of the objective lens is directly proportional to its length.

1. The function of the eyepiece of an optical microscope It is to further enlarge the real image that has been magnified by the objective lens and has a clear resolution, to the extent that the human eye can easily distinguish it.

The difference between eyepiece and objective lens in optical microscope The eyepiece and objective of a microscope are both convex lenses, with the difference being that the focal length of the eyepiece is shorter,

2014124 — Yes, you can cut glass on a CNC machine. All you need is a diamond burr or glass drilling bit, high speeds, low feeds, and lots and lots of coolant.

2. The relationship between the eyepiece and objective lens of an optical microscope. The objective lens has already distinguished the fine structures clearly. If it is not magnified by the eyepiece, it cannot reach the size that the human eye can distinguish, and then it cannot be seen clearly; However, fine structures that cannot be distinguished by the objective lens cannot be seen clearly even after being magnified by a high-power eyepiece. Therefore, the eyepiece can only serve as a magnifying lens and will not improve the resolution of the microscope. Sometimes, although the objective lens can distinguish two objects that are very close together, the distance between the images of these two objects is smaller than the resolution distance of the eye, so it is still difficult to see clearly. So, the eyepiece and objective lens are both interrelated and mutually restrictive.

Eyepiece: Installed at the upper end of the lens barrel, usually with 2-3 pieces, engraved with symbols of 5 ×, 10 ×, or 15 × to indicate its magnification, usually equipped with a 10 × eyepiece Objective lens: Installed on the rotator at the lower end of the lens barrel, there are usually 3-4 objective lenses, among which the shortest one engraved with the "10 ×" symbol is the low magnification lens, the longer one engraved with the "40 ×" symbol is the high magnification lens, and the longest one engraved with the "100 ×" symbol is the oil lens. In addition, a circle of different colored lines is often added to distinguish between the high magnification lens and the oil lens
