Eyepiece: Lens close to the human eye, marked with words such as 16 x or 10 x, indicating that the eyepiece magnifies 16 or 10 times. Features: No thread.
The longer the eyepiece, the smaller the magnification
The shorter the eyepiece, the greater the magnification
Objective lens: A lens that is close to the object, marked with words such as 10 x or 40 x, indicating that the objective is magnified 10 or 40 times. Features: Threaded.
The longer the objective lens, the greater the magnification.
The shorter the objective, the smaller the magnification.
Tips:The length of eyepiece and objective lens is exactly opposite to the law of magnification
Installation of eyepiece：
1.Insert the eyepiece directly without rotating it!
2.Do not touch the eyepiece mirror during installation (if your hands touch the eyepiece mirror, it will pollute the mirror and affect the observation).
Installation of the objective lens
Objective lens installation precautions:
1, first align the thread on the objective lens with the thread on the converter and then turn (the key to the installation of the objective lens), otherwise how to turn can not be installed.
2, do not touch the objective mirror during the installation process (if the hand touches the objective mirror, it will pollute the mirror and affect the observation).
3. In order to prevent the lens from falling, both hands should be used.
Precautions for the placement of eyepieces and objectives in the lens case:
1, the mirror face up (the hand can not touch the mirror during the placement process).
2. The objective lens is transferred into a threaded groove, and the eyepiece is inserted into a non-threaded groove.
3. Note that the length of the eyepiece objective matches the depth of the groove.
4. Pick up the lens box lid vertically after opening, so as not to bring down the lens.
5, remember to put the lens box back to the original position after use.
