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”.
Precautions:
(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.
(4)When using the 40x magnification objective lens,the objective lens may touch the specimen.Please be careful.
Operational Instruction
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!
A Set of Slides

How to create your label?
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.
Tips:If the image during the observation process is blurred, because the focal length is not adjusted to the proper position, Try to adjust coarse/fine focusing knobs.LED lights will be affected by the environment and using time.A well maintained microscope will keep its optical quality for years and thus maintain its value.

We got this microscope for homeschooling. The first that arrived, the bottom LED light never turned on, making it impossible to use unless you use the flashlight on your battery. Had Amazon send a replacement. As soon as it arrived, unlocked it to see if it worked and, nope. Same issue. Getting a refund and going with another brand this time.

This is what you call a good investment. I bought this for my young daughter who absolutely loves it. Me and her have spent many hours looking at different things. She was a newbie to this and so was i. It is not difficult to figure the microscope out at all. Just needs a tiny bit of practice. She managed to do it in a few minutes :) the microscope is sturdy. Worth every penny.

this was just what i was looking for in a family microscope. easy to use, fairly simple to get clear images. My kids are 5 so they lost interest quickly on each slide but i believe they will use it more and more as they get older.

I have been impressed with this for the price and quality. It arrives in a whole carrying case, with a dedicated place for the included slides, as well as the other optical pieces. This makes it easy to safely store in between uses. My kids, from ages 4-10 are able to use it independently. Excellent addition to our home classroom!

a good microscope for a persons first microscope it is well built and not like the cheaper plastic versions the instructions could be better no explanation in detail on what lens to use for different applications no instruction at all on the phone adapter you can work it out but would be better if given a bit more detail in the instructions other than that it is a good quality for the money , mine was bought as a christmas present for my grandson and hese very happy with this

The original microscope I received had broken eyepieces--every eyepiece was broken--but it was quickly replaced and the new one is perfect. So customer service must be congratulated--it was quick and efficient. The eyepieces on the new microscope fit perfectly and work. I got the microscope to check out the life in our pond and it works for that, although therre are no slide covers so I needed to purchase those to use it effectively and make my own slides.The microscope came with a selection of prepared slides to get used to using the microscope and it was a nice selection that was interesting to view. There were also a few clean/blank slides to use but as I mentioned, there are no slide covers. I did use the slides with drops of pond water without slide covers and it is doable, just not the best.The microscope itself is very well made--mostly made from metal. There is a light that shines up from the bottom and one that shines down from the eyepiece area onto the subject. I can pick one or the other source of light via the on/off switch which rocks to the right for the upper light and rocks to the left for the lower light. The entire kit is encased in a really nice small case with a handle that protects everything very well. A cell phone holder is included to hold my cell phone so I can photograph whatever I'm looking at via the eyepiece. That worked surprisingly well for me. There is also a pipette to help prepare slides as well as a few other odds and ends.Overall, it's a really really nice microscope set. I only took one star off because of the lack of slide covers so that I could immediately use the blank slides to prepare my own using our pond water. It's a really minor complaint and isn't really a problem with the microscope per se.
