Celticbird Smartphone Camera Adapter for Microscope Eyepiece Tube 23.2mm - Built-in 16X Microscope Eyepiece

I ordered not knowing exactly how it was going to work. I was expecting it to slide over the outside of the tube and was prepared for it to be a little wobbly. At first, I was disappointed because it was too small to go over the outside of the tube. Then, I remove the microscope eyepiece and inserted the adapter into the tube. It was so amazing. I was able to see in great detail and take pictures of what I was seeing. It works better than expected. After tightening the eyepiece set screw, it was very stable.

Snug on phone and sets well into microscope tube. Clear optics. The only drawback I see is that you are stuck with a 16x optic. It would have been nice if they had a tube that would slip over the eyepiece you might want to be using instead of having to use their eyepiece itself, so you could use higher magnification eyepieces. But still worth five stars.

Works amazingly well and allows you to use modern mobile phones’ excellent cameras for microscopy. The only issue I have is that the lens on the insert could be much higher quality without adding much cost. Seriously, you could sell twice as many for twice the price. I wish at least there was a pricier option for a quality lens.

This product does not work. I wish I hadn't purchased so far in advance so I could return it. It's very flimsy and blurry

Great for use with microscopes . My students loved using their cell phones to take pictures through the microscope . Very steady when using an i phone

pleasantly surprised - it actually works

This is a great device, and it works perfectly with all Galaxy phones that I own. What I really like is that I do not have to remove my phone case to use it and its a thick case. It can be a little tricky to line up with the camera but once you have it lined up you should only need to fine tune it next time you use it.

Didn't work/fit on my microscope!
