This Microscope magnifies well but it is not high enough in power to view microorganisms in pond water. You can view the small print on a dollar bill or look close at an object, beyond what you can normally see.There are two good words to describe a microscope/magnifier. The magnification and the resolution. High magnification is useless if there is not enough resolution. Think of what you see if you zoom into a picture you took on your cell phone. As you zoom in you see more detail but at some point the detail stops and continuing to zoom provides nothing of value. How much resolution you need depends on what you are looking at. You could zoom into text letters with lower resolution and still be ok because you can make out the letters.I was able to confirm the 200x magnification on a 23” monitor. But as stated above, magnification is not the only thing that matters. You could project the same image on a 52” TV and get further magnification but that does not mean you will see anything further or see any value in the image. I think 200x is about the limit of what is useful.The best way to describe the magnification is with something we can all look at and understand. For that I used the US dollar bill. This camera will magnify George Washington’s eye in a one dollar bill to fill the entire viewer. Picture included to see the maximum magnification using George Washington’s eye from the dollar bill. It doesn’t matter how big your monitor is, you still get the same image in the frame of the viewer. A larger screen just has a larger eye in a larger frame but that does not mean it shows more detail.This web camera can run on any device that supports web cameras. You can use any software you can get that works with web cameras. So yes, this works on Linux and it works on cell phones and tablets that support USB cameras. Not all phones or tablets will support USB cameras. I have tried the Linux Camarama Webcam Viewer software from the Ubuntu software library. It works as well as the Cheese application. It will likely work on any web camera software because this is just a web camera. This camera works on my Android Pixel XL phone as well using a OTG cable. The OTG cable is a cheap cost connector that lets you convert the micro USB to a standard USB connector. This allows you to use a USB drive to back up software or pictures from your phone. You do need the OTG labeled connector, it is not just a simple USB micro to USB connector. And of course you phone needs to support OTG. Many newer phones support it. The Google pixel phones and the Samsung Note5 support OTG as well as many others. There are a couple steps to turn OTG on these phones. Research phone OTG and turning it on prior to attempting to using the camera to save some frustration. For the android phone, there are may webcam apps, I tried a few and liked the Endoscope app but it has low resolution images, like 640 x 480. But this is enough for many things. There are others, try them all if you want. Some will store much larger images.Resolution: The camera description states the camera sensor provides 1600 x 1200 image resolution size. However not all software supports that. Using the android Endoscope app, the images are saved as 640 x 480 (0.3 MP) size. The Linux Camarama Webcam Viewer software will display the image in 3 different views, Small, Medium, and Large.The Small image was saved as 160x120.The Medium image was saved as 800 x 600.The Large image was saved as 1600 x 1200.CameraFi Android applicationCan select different video sizes from 640 x 480 to 2048 x 1536, 2592 x 1944 at1 0fps,1600 x 1200 at 30 fpsSo the choice of software/application can change the resolution of the image saved.The Linux Camerama app saves the files to png type. The android app stored the file as a jpg. The type of file is determined by the webcam software not the camera. So if you want jpg files, find an app that saves as jpg. Png file format probably makes the most sense for storing the detail of a magnified image. jpg files have too much compression which does not work when trying to capture details of a magnified image.The light is adjustable but can be too much for looking up close at shiny objects. It is very hard to look at a diamond because of all the glare. Can turn off the light and use an external light which is better in some cases. It is helpful to use reflected light or light diffusers, on some objects.The stand is stable enough. It has enough weight to it to hold the apparatus stable while turning the focus knob. With all the knobs on the stand locked, the camera is stable. It does not move in any direction due to vibration or tilting of the stand. There is a radial pivot on the camera holder. It can move radially and does not have a lock but it is does hold in place well. It will not move due to any small movements, you have to put some pressure on it to move it. Appears to be a rubber on metal grip. A quick pull on the camera wire could cause the camera to move radially but this is not something that would easily happen if you are careful.There are two black turn knobs on the standup post, the one with the gear notches. These two knobs are locked together, turning one turns the other. This set of knobs will raise and lower the camera on the stand. At first I was loosening the lock nut then using the larger knobs to move it up and down. This works but you have to lock the position before removing your grip from the larger black knob. Otherwise the weight of the arm will cause the arm to drop all the way down. Then I found if you tighten the lock nut snug but not any tighter, you can move the larger knobs and the arm will not fall when you remove your hand. This is the way to use the device, it works really well.The camera comes with several attachments. At first I didn’t think much about the attachments. Then I decided to look more closely at them. They are helpful for viewing some things. For instance, one attachment is a plastic piece that fits over the camera tip. Does not look like it would do much good but it does help look at objects up close when hand holding the camera. Given the magnification, it is hard to hold the camera still enough to view something clearly when using the higher magnification. Using the plastic tip, put the tip on the camera then place the end of the tip up against a table and focus the image. Then you can just put the tip up against anything else to see that object in focus without using the focus knob and not dealing with your hand moving the camera around. This works really well to view up and down the edge of a knife to see the edge in detail, see attached pictures. It also helps to look at your skin, you can just move it around on your skin and see it in focus. This is not easily done without the attachment. There is another attachment that looks like the end piece used on that instrument your doctor uses to look into your ear. With that piece you can do the same thing, focus it first then put up into your ear and likely need to fine tune the focus to see. You can see inside your ear well with this piece. Without the piece it is hard to focus on anything. The other attachment is a long tube, I think to look inside something, like your mouth. These attachments make it much easier to focus on certain types of things. The last attachment is the 90 degree mirror. It works for looking around a corner, like into a wall or something like that.The camera will focus up close, around 5mm from an object. This is not an exact measurement, I just held up a ruler at what I found to be the closest I can get from a penny. On the other end, the camera can focus to infinity, meaning you can see around a room like a traditional webcam. Nothing special there, don’t really see much use for that given the stand.Summary: The camera works well for looking at images magnified up to 200x. The camera is compatible with a lot of third party software. I have confirmed it works on Linux, Android, and Windows 10.Took two pictures of the same dime, one at 800x600 and the other at 1600x1200. Other pictures included too.

Purchased this for a single type of use, and for me it works and serves it's purpose. I would classify this as a hobby microscope.

Pour un numismate c’est un article super.

I found this to be an excellent pen microscope / boroscope. For the money it is an deal. The stand is made of anodized aluminum. The finish and machining is crude but works. For the price, the quality of the stand is excellent. The knobs are of ABS plastic, The cord is a Mac-style white USB cord with a dimmer. The dimmer has a still capture button. The focus ring is on the pen at its base and works reasonable well. The base is 5-3/4" x 3" and is large enough to accommodate the largest object that is viewable by the scope (about 1.5" x 2"). The device comes with 5 accessory attachments in high quality medical-style ziploc pouches, and a CD. The accessories are: (1) a protective sleeve for the pen, (2) a clear plastic offset attachment that allows the pen to be held against a flat object, (3) a clear plastic cone attachment that would be appropriate for using in a nostril, (4) a black plastic narrow neck attachment that would be appropriate for using in an ear canal, and (5) a right-angle mirror attachment. The CD has several instruction documents, including a well-written troubleshooting document, and two viewing programs, AMCAP.exe and ehe.exe for Windows. There is also a Mac folder with "WebCam Monitor v2" software.The camera functions like a web cam and will focus at infinity all the way down to about a millimeter which for my computer monitor was a 200-to-1 magnification. Since the image is 1900 x 1200, the smallest resolvable object would be about 0.001 mm in diameter, or 0.00004". I was able to photograph a human hair 0.001" or so in diameter (see photo below). The photographs also show typical views of a coin and a detail on the same coin. The ability to adjust lighting with the dimmer was crucial to getting good results. I was also able to use it like a medical boroscope, examining my own mouth.This device could be used for a variety of purposes, such as biology/naturescope, simple medical boroscope, metallurgy, numismatics, taking pictures of small objects like insects, electronics, viewing hard to reach areas, etc.The AMCAP software included is a free web cam viewing package which works reasonably well and operates fine on Windows XP, my platform. If you are doing serious work, you may want to get a more professional web cam viewing software package.
