Can anyone recommend a decent LED lighted microscope that I can use with my cell phone to take pics with? Pawing through Amazon, there are quite a few choices and I'm sort of leaning towards the Carson brand. Eyes are getting older and don't see as well like I used to. Basically want something that I can zoom in on 19th century USA and see those pesky secret marks and other stuff like that better. Then be able to snap a decent photo or it. Had seen the Carson MicroBrite Pro 60x-120x LED Lighted Pocket Microscope with Aspheric Lens System and Smartphone Digiscoping Clip (MM-350) and thought that might be okay, given the price.

Anyone use one of these or something similar? Or have any good recommendations?

I have an iPhone and find that the built-in Magnifier works very well. Plus I downloaded another free app called "Mag Light" which does much the same. Both can zoom in pretty well, add more lighting, and take a picture so that you can examine it without being perched above the stamp the entire time. You may want to check into those options rather than purchasing something else to carry around.

I use Currency Detecting Microscope 60x. It is a very simple inexpensive toy with internal Normal and UV light sources. Currently it is on Amazon for $7.53.
As example I attach image of two stamps with different paper type, and images of the same stamps taken with my cell phone with microscope attached. In this case I used UV light to determine fluorescent paper type.

Hi, how do you attach it to your cell phone? I assume when using UV light looking at the screen will not harm your eyes? Apologies if these queries are a bit basic

crispinhj, picture shows the microscope attached to my cellphone. As for UV light - this particular light source is not specifically dangerous (It is so-called "long UV range"). And when you look at your screen it is definitely safe.

If you look at the screen you see light from your lcd screen which does not emit uv light.

If you are thinking of directly looking into the light of that miscroscope, its power is way too low to cause any damage to your eyes. From the look of it, it uses LEDs which emitt light in the 395nm range (not the "normal" 365nm long wave uv better lamps do). This wavelength is very close to blue light hence why you see a very bluish sample picture. This may sometimes obfuscate the result.

If you use a 256nm lamp (short wave uv), you must avoid being in the light path (direct or reflected from a surface) as this wavelength damages your eyes.

What you see on your monitor also depends on the blue wavelength range sensitivity of your camera. I bought a TOMLOV 602 Pro digital miscrosope recently and it has a low-end 4M (not as advertised a 24M) Pixel chip inside. Basically unusable for taking pictures with long-wave uv as the sensitivity is very poor.
