lots of missing data.. Id like to have known more about some of the ones missed out too

Hi, you are correct, this is an error in the video, and I forgot to pinch to zoom because the FOV of some of the smartphone microscopes covers all of the FOV that your camera usually has. The biggest issue is that I didn't pinch to zoom with the Apexel macro lens. Once you pinch to zoom with that one it brings the magnification to slightly less than, but effectively equivalent to the black mobile microscope that I recommend.

GrowPRO Mikroskop für Smartphones

Glad you are enjoying your mobile microscope! I never realized how expensive international shipping is and how high tariffs are in some countries until I started selling products internationally. We are stocking full sized microscopes in a couple weeks, hopefully we will be able to find you one that has reasonable costs and shipping to your country. Fingers crossed!

At that price range you could totally afford a monocular compound biological microscope with a smartphone microscope adapter, that's the direction I would go in at least. At that high of a magnification, holding the setup still enough becomes the biggest challenge.

The challenge is that bacteria require one of the highest magnifications of any sample, and also need either low NA transmitted illumination or to be stained, which makes it impractical to observe bacteria with a simple smartphone microscope. The simplest and cheapest way to do this would be an inexpensive compound biological scope and pair it with a 'universal' smartphone adapter. Out of our lineup, the MS-205T would be the cheapest microscope that will accomplish this.

Sure does!

Not with a handheld phone microscope adapter. The problem is that the XY axis needs to be held extremely rigidly for focus stacking to work, far more rigidly than your hands can hold it.

Keep looking, you can find some for $3!

Yes, works great on iPhones! We recommend downloading the Yammer App for iphone which gives you more control over your camera and putting the smartphone microscope over the telephoto lens. This advice should apply to any smartphone microscope.

can't find any camera app called yammer.. @@micro_safari

Do you have a link to the specific model that you are talking about? I think I may have tested a Carson one a couple years ago but it didn't make it into the video. I either gave it away or it is sitting in one of my equipment boxes.

@@micro_safari mm-250/350/380 are suitable for smartphones...i had the zorb one, but it didn't function on my mac, and i was thinking of buying one of those!!! (maybe micromini!!!)

@@micro_safari carson it's an optical products company, and i'm quite happy with it!!!

​@@yannisgk We've done quite a bit of exploring the wholesale purchasing of microscopes in the last couple months since we are going to carry our own inventory of microscopes, and I recognize most of their microscope selection as being white-labeled chinese wholesale microscopes. That's not to say that they are bad quality products, and they might manufacture some of their own products, but for the most part they are just reselling chinese microscopes with their brand name on it and not making that part obvious.

@@micro_safari i don't believe that their microscopes are china's origin....i haven't found a chinese microscope (at least), EXACTLY as theirs...resembling them, yes, but i am sure they are not rebranded....in opposite, they are very good products for their price!!! i understand you must market your own products, but don't put "mud" on carson!!! thanks!!!

I'm deep enough into microscopy at this point that things that are obvious to me I forget are not obvious to most people. Due to the physics of how light works, high magnification phone microscopes that you hold with your hand are practically useless. The depth of field is so shallow that you can never get an in-focus image, you need a high NA illumination source to resolve any detail at that magnification, and it is impossible to hold your hand still enough that the field of view isn't constantly moving around. The majority of the body of a standard microscope that can practically image high magnifications is devoted to holding your sample incredibly still, allows you to move it microscopic distances, and illuminates the sample in a very particular way such that you can resolve details near the wavelength scale of the light. Hope this helps!

I gave the brand names of all the microscopes that had names. Most of the models were purchased directly on Alibaba. This review was more intended to go over the physical designs of different smartphone microscopes rather than specific brands since 90% of companies are just white labeling anyway. If you'd prefer to purchase our recommended smartphone microscope not through us, just look for mobile microscopes that have the same physical design. You should be able to find it elsewhere for cheaper, but we can't verify the final product quality since we are working with a specific supplier that charges more but also has a history of better product quality. We are also QA'ing each mobile microscope individually. Cheers
