To focus you move the wheel controls on the side of the base unit this works ok, but does use plastic gears so can be hard to get just in the right position. The image below shows the differences with the 10x, 60x & 200x magnification. You can launch the software, or press the camera button on the microscope and automatically launches this software. Though I have just downloaded the latest drivers from there website HERE, This install the driver for windows, I am using windows 7 32bit, it also installs a basic capture application called Camapp, this software allows you to capture a still image or video. The software that came with the microscope had the windows drivers and videostudio.
The microscope unit slots into the base, you have two light sources one directing down from the lenses and one on the base, these can be alternated between the lamps or both on or off using a button on the top of the unit. The microscope has a resolution of 1.3 megapixels, with 10x, 60x and 200x magnification. Just over a year ago I brought a Traveler USB Microscope from Aldi supermarket, it was on offer at £29.95, to be honest was just an impulse buy and really since I had brought it not really used it that much but thought I would share my thoughts and show some of the images it can produce.
