There is a cylindrical drum you can twist for focusing the microscope. As you turn it an internal lens moves up and down the barrel, changing the distance to the specimen. On the drum, there's a scale, with markings from 20 to 400 on it, that is quite misleading -- it suggests that you can optically zoom continuously from 20x to through 400x. But that is not the case. Instead, there are two fixed magnification levels, one nominally 20x and one about 400x, corresponding to two different focus locations, and they do not correspond to the locations on the scale you would expect!
Using it at 20x power:
If you place a specimen, like a piece of paper, directly under the microscope and place the clear plastic end of the microscope directly on the paper, the 20x focus occurs when you turn the drum beyond the top of the scale, past the 400, then a little past the 20 mark as the scale starts repeating. At this focal point the internal lens is moved up the tube, far from the specimen. The field of view is 13.5 mm. You can then move the microscope farther from the paper, readjusting the focus as necessary.Read more ›
It is a great little toy to play with and is a lot of fun. However, I am a teacher and had hoped to use it in a more serious manner in the classroom. I liked the idea of being able to make on-screen measurements and unfortunately, that is the most lacking feature of the product. With my version of software, I am able to enter in a magnification of 400 while making measurements. It was pretty accurate showing .97 mm for one tic mark on a ruler. I know my degree of accuracy in drawing the line was certainly not within .03 mm so I am happy with the results. The reason I am rating it a 3 is simply because of the difficulty in this measurement process. Because the measurements can only be made at 0 distance (i.e. the object at 0 distance from the end of the clear plastic ring) it limits the types of measurements that can be made. For example the field of view at x20 is about 13mm as Paul points out. If I want to take a picture of anything bigger than a dime (or even a dime) I can't do so because a dime is 18 mm in diameter and won't fit in the field of view. If I back off a little bit and refocus, I can get an entire dime in the image, but then I have no means of determining the actual magnification ratio. Because this limits my use in a school lab setting, other than just capturing images and video which in itself is useful, I rate it down to a three. In all fairness, I don't know the capabilities of competing products such as the high priced pro-scope so they may all work this way.
Another issue is the funky stand that comes with it. It is too short and inflexible to be useful. It really needs to be twice as long as it is with a second joint between the two arm segments.Read more ›
I have a case started with Veho, and I'm hoping they will RMA the scope and send me the v2. There is no need for this much confusion! I will revise this review if they resolve my problems.
Veho UK eventually responded and simply passed the buck. No advice on how to ensure that I get a v2 scope, and no offer to exchange the item on their own.
Veho UK decided to grace me with a solution and suggested that I buy the scope through their website. Turns out, it's significantly higher-priced there than at Amazon, and they offered me a meager discount after all this trouble. I sent the scope back to Amazon and now use the Carson orb instead. AVOID Veho!
