Usb Microscope Modification. Increase Working Distance. Focusing Distance Hack. 

i took mine apart to do this modification, but to my suprise now they made changes to do this mod with no destruction. they changed the soldered pins to little screws so the board comes out and back in very easily. and instead of the press-fit tube, they put the lens on a fine plastic thread so you can just screw it in farther and reassemble everything with no soldering or cutting. part of the amzon title is Jiusion 40 to 1000x Magnification Endoscope for the one i got. with enough light you are easily able to focus on any distance(up to like 20 feet) with it threaded all the way in, although the quality does go down a lot with less light and more distance.

cool video 👍 yeah the silicone glue got me too...

Interesting mod. Why you don't show the mod result as it will show on your PC? I think it would be interesting to see the actual increase in working distance, even though at expense of a reduction of the magnification.

Thank you for good video. How much room do you have from board to microscope? enough room for soldering small parts?

I would like to see someone make a telescope out of these.

So..... no comparison images or measurements for the modification performance?

It will be nice if you show the resulting magnification.

READ THIS BEFORE OPENING YOUR DEVICE: There is chance that you can achieve the same result without opening the microscope. Remove the transparent cylinder at the bottom. Increase the zoom/magnification to maximum by turning the silver knob to the right. That way the pointy tip of the microscope should come out at the bottom and you should also be able to see it's plastic thread. Now you can reach the tip with you fingers (make sure they are clean just in case) and twist the tip in, as much as u want. The more you twist it in, the higher the working distance but also the further away your LEDs are and the therefore the image quality decreases. You might want to use a second light source then. Which method works depends an what generation of these devices you have. If you have to open it anyways, make sure no dust gets onto the sensor and inside the optics! I didn't know any of that. When I noticed I didn't have to open it at all it was too late. I put everything back together and then noticed stains on my image. Dust got inside the microscope. I opened everything again and cleaned the sensor and the glass and put everything back together just to realize that made it worse. Invisible dust particles and fibres from my tissue always remained on the sensor. 15 tries and lots of new tissues later I got lucky. Finally I got an acceptable result but the image is still not as good as it was before and maybe I also removed an important coating with that... It took me 3 hours to do something that takes 5 minutes, but I am still thankful for this video! Without it, I would never have known, that I can increase the working distance at all and would have sent it back as it is. So thank you and greetings from Vienna 👋🏻

I'm guessing this mod while increasing focus distance also will effect the magnification minimum and maximum unless the lens is not changed at all for where it is set in the tube and that extra cut off was just left there for no reason.. maybe to save on manufacturing cost or to calibrate the magnification to exact levels?

What was the working distance before mod compared to the distance after mod? Basically the working distance gained from this modification? Tha

very good video

Hi sir, thanks for the video. Can you provide the links for the testing part? Because I have search for 'microscope' but still could not find it

Would have been nice to see the results of this mod

So he shows the mod but not how it looks AFTER he does the mod?

If the pcb is removed from the two metal rods that hold it in place and these rods also are powering the leds of the microscope and place extension pieces in both of them so when the pcb with the ccd camera is soldered back then will have a longer distance from the lens and this also will increase the focusing distance also.Next i will experimenting with this to test it.

Wouldn't the lens crash into camera sensor after cutting the distance in half ?

Merci de me répondre . Je vous demande par quoi remplacer l'objectif de mon microscope x800 perdu ?

but you must show the results!

AVEC QUOI REMPLACER OBJECTIF PERDU . MERCI

I have one can not to work on my Samsung phone
