diy x200 microscope

Hello !
Ladies and gentlemen, do you want to explore the world in the past? ?
I bet most of you do.
But the instruments needed are very expensive.
But there is a solution that can get good results with just a few dollars.
To make highly amplified images, the microscope uses a high power lens.
We can make it as long as we have a high power lens.
But under a normal microscope, the image will focus directly on our eyes.
This requires a very complex lens design.
By using smartphones and high-power lenses, we can do this in a very simple way.
It just needs to keep the lens in front of the smartphone camera and touch each other.
Then through the camera, you can see an image that is highly enlarged.
But in order to observe the sample stably, we must establish a device. So let\'s move on. .
In this project, we use a high power lens that is very expensive in the market.
But we can find them in DVD/CD reader head.
In fact, in order to read the burning data on a microscopic scale, they have a high magnification capability.
As shown in the figure, safely remove the lens from the reader.
Even a small scratch will ruin it.
In this project, we will use a high power lens that can be found in a DVD/CD reader with a smartphone camera to get a highly enlarged image.
I mentioned a copper-clad plate in the material list.
It\'s supposed to be a copper plate that can hold a smartphone with just one board.
Any material can be used.
I chose a copper plate for easy cutting and drilling. Materials--1.
1/2 PVC pipe (about 20 cm)2. Glass sheet -
About 25 cm x 16 cm 3.
Nut and bolt Collection 2mm \'\'1/2 inch in diameter.
Copper bag plate or acrylic 5.
Lens for DVD/CD reader 6.
Acrylic tools-1. Hack saw 2. Drill(2 mm drill bit)3.
In order to get a stable view of the sample, we have to do the whole installation stably.
To do this, we use the copper plate to simply install the smartphone.
The size of the motherboard will be 2 m longer than the smartphone, and now we have a motherboard suitable for the smartphone.
The next step is drilling the lens and four screws.
I have to explain something about the design before that.
The mobile phone holder needs a mechanism to focus the settings perfectly on the observation sample.
To do this, I will use four screws to change the distance between the lens and the sample.
These screws will be placed in four corners of the support board.
When drilling for the camera, it takes time and perfectly marks the point where the camera is located.
After drilling, it\'s time to place four screw bolt nuts in four corners.
By using strong glue, align them perfectly with the drill holes.
Make sure you don\'t spill glue on threads.
After placing four nuts, the time has come to place the lens.
Before cleaning the lens to the rough edge of the drill.
Then put the lens on the drill.
2mm of the holes will be perfectly mounted on the lens and will not fall.
Then glue the lens with a little glue.
This is a very tricky part.
Be careful, other wise minor mispositions can lead to wrong results.
Now that the phone stand is done, we have finished the stand.
So now we need a platform to save the sample and save the phone holder.
I chose a plate of glass for this.
When the smartphone is free to move and observe any part of the sample, the sample can be placed directly on the stage.
This can be a bit confusing, but it will be clear in the image.
We need lighting to see through a microscope.
To make room for the lighting mechanism, I raised the stage with four PVC pipes about 5 cm in length.
Then set the lighting mode under the glass stage.
In my case, I use the phone flash.
This is simple and perfect for this project.
I have tried a lot of light sources and the smartphone flash works best.
That\'s all about the structure. let\'s start testing it.
Now we have the microscope ready.
Let\'s see how to deal with this.
First of all, we have to balance the phone holder.
To do this, you can change the height of the phone holder by rotating the four screws.
Keep height about 2-
3mm is roughly balanced.
OK, now you have to fully align the camera of the phone with the lens on the phone holder.
This can be done by opening the camera app and aligning until you get the perfect view.
After that, we need a sample to observe.
As you can see in the picture, I placed two onion tissues.
Because we have enough space to place more than one specimen.
Then turn on the flash.
Now you can slide the phone holder onto the glass until the camera view shows the defocus image of the tissue.
Focus can be done with two screws closest to the camera.
You won\'t believe the results of this microscope.
It is hard to believe that with this simple DIY micro mirror, there may be such a result.
The magnification is about 200x.
Here are some samples I have observed.
Cell walls and nuclei are clearly visible.
When blood cells gather together, they seem to be red.
They can be seen in distributed form like small bubbles.
I took some water from my backyard pond and I was blown out. . .
This is my favorite.
This is all for these friends. .
