Microscopes are mainly used to magnify tiny objects into instruments that can be seen by the naked eye. The optical microscope was first created by Jansen in the Netherlands in 1590. The optical microscope is mainly composed of eyepiece, objective lens, stage and reflector. Both the eyepiece and the objective lens are convex lenses with different focal lengths. The focal length of the convex lens of the objective lens is smaller than the focal length of the convex lens of the eyepiece. The objective lens is equivalent to the lens of the projector, and the object becomes an inverted, enlarged real image through the objective lens. The eyepiece is equivalent to an ordinary magnifying glass, and the real image becomes an upright, enlarged virtual image through the eyepiece. Objects from the microscope to the human eye are all inverted magnified virtual images. The mirror is used to reflect and illuminate the object being observed. Reflectors generally have two reflecting surfaces: one is a flat mirror, which is used when the light is strong; the other is a concave mirror, which is used when the light is weak to converge the light.
WHAT IS A MICROSCOPE?A microscope contain 2 lens systems:the eyepiece and the objective.We’re presenting this system as one lens each so that the concept is easier to understand.In reality,however,the eyepiece,and the objective in the revolver are made up of multiple lenses.The lower lens(objective) produces a magnified image of the prepared specimen.The picture,which you can’t see,is magnified once more by the second lens(eyepiece),which you can see as the “microscope picture”.
(1) Before using the microscope, you should be familiar with the names of each part of the microscope and how to use it, especially the characteristics of identifying the three types of objective lenses.
(2) Most of the specimens observed in the practice of parasitology are colorless and lighter in color, so attention must be paid to the adjustment of light.
(3) When observing fresh specimens, a cover glass must be added to prevent the specimen from being dried and deformed due to evaporation or contamination and corroding the objective lens. At the same time, the specimen surface can be leveled and the light can be concentrated, which is beneficial to observation.
1.Put the eyepiece in the eye tube.
2.Connect the power or load three AA batteries.
3.Clean the specimen,place the coverslip upward in the center of the stage and fix it with the tablet.
4.Rotate the converter and set the objective to lowest magnification 4x.Watch into the eyepiece while slowly rotating the coarse focusing knob.A unclear object can be seen at this stage,and slowly rotate the fine focusing knob until a clear vision.
5.Adjust the filter disc or the brightness of the light source while looking at the eyepiece until the condition is appropriate.
6.Objective lens can be replaced according to actual needs:adjust the converter clockwise:4x→10x→40x.
Note:Make sure that you never over-tighten the focus knob!Always move the stage to the lowest position before changing the objective setting to avoid any damage!
The microscope comes with a set of slides, including 10pcs prepared slides and 5pcs blank slides： plants, insects and animal tissues.The microscope slides are perfectly compatible with all educational or professional microscopes.
It comes with a smartphone holder.Suitable for any smartphone,included series of iphone,series of samsung.So that you can take picture or a video,to share with your friends,classmates,families or collect them.It’s great.
Two wide-angle eyepieces(WF10X/WF25X) is made of full-optical glass lens, with metallic lens body. The main function of the eyepiece is to re-enlarge the real image obtained by the objective lens, thereby forming a clear virtual image at the clear viewing distance.
With 4x,10x,40x 3 high-magnification achromatic objectives,metal mirrors,optical lenses, clearer imaging.The light is used to image the object under inspection for the first time. It is the main component that determines the resolution and image clarity of the microscope.
Up and down two wireless LED light sources, easy to operate, not affected by external light sources. The upper light source is suitable for observing opaque objects, and the lower light source is suitable for observing specimens.
With 3 objective lenses,2 eyepieces and 2x Barlow lens,offers 10 levels magnifications:40x 100x 250x 400x 1000x/80x 200x 500x 800x 2000x.The microscope is designed for kids students adults to explore and understand the fantastic world of life science.It’s an amazing tool for science Lab Class Home Study.

1. Take the observation material for slicing, pay attention to the slice to be thin;
2. Use a dropper to suck up 1 to 2 drops of water and place it in the center of the slide.
3. Tear off a small piece of the observation object with tweezers (the material should be turned into a thin sheet and placed in the droplets on the slide and try not to shrink the material.
4. Grasp a clean cover glass with tweezers, first touch one side of the cover glass with a small drop of water diagonally, then slowly lower the cover glass to cover all observation materials
5. After making it, you can put it under a microscope for observation.
