In the holder foot the two supplied AA batteries had to be lodged, - and already burned the transmitted light, which of course you can turn off.
Now for the main part, the microscope.
First of all: It is of course far from a proper microscope, rather an interesting research toys for children.
The question is whether you can use it anyway for the intended purpose.
There is a manual in several languages and in a CD, in addition to the installation software, instructions for experiments can be found with a microscope to see the.
It is also, in addition to the batteries already mentioned, a box with slides and finished preparations included.
So you can experiment with the same times and try the microscope.
The microscope has two levels of magnification, is given a 20-fold and 200-fold.
The second stage is achieved by rotating the focus tube as long counterclockwise until the second focal plane is reached.
The alleged 20-fold magnification was measured as 27.5 times.
About this 'microscope' and its enlargement already has so much speculated and written also incorrect, so I want to explain exactly once.
Actually, it's not a microscope, but a macro digital camera with a USB port. (Similar to a Web cam)
Therefore, one can not really speak of an increase, but rather, as with a digital camera, by a resolution.
The camera has a chip with 1600 x 1200 pixels sensor, thus making the camera an area of about 1.45 x 1.09 mm from.
Most PC monitors have a dot pitch of 0.25mm. This so 1600 x 1200 pixels displayed 300 mm in size on a monitor 400 x,
which in turn corresponds to a "magnification" of (400mm / 1.45mm) 275 times approximately.
The resulting image can be clearly seen in reflected light as well as in transmitted light over the area.
The objects are relatively easy to see, with little sharpness and brightness drop on the edges.
I was a bit surprised, because that is actually more than one would expect from such a cheap part.
By pressing the top button on the microscope you can save the image currently shown on the monitor in JPEG format.
However, this is a fumbling, because as soon as I touch the button for triggering, the cut-out and the focus shifted.
This is due to the poor quality plastic holder. Unfortunately, this falls into the quality somewhat.
The carriage on which the microscope is fastened and can be moved up and down,
wobbles horizontally several millimeters, so that you lose the focus on the subject quickly out of sight.
It's really working a puzzle with this little device.
The manufacturer should make improvements necessarily, because that reduces the quality of the otherwise acceptable device very.
But I think for the price you can hardly expect a total, since the microscope holder with less cost than the same without bracket.
