The Aven zipScope is a tabletop, 2. This digital microscope enhances the resolution of an object or image, and connects to a computer for image display. It is commonly used for quality control QC inspection, medical and scientific research, geology, mineralogy, chemistry, and for printing and textile inspection.
This microscope has an adjustable magnification of 10X to 50X, and comes in an all-in-one, compact lens. The frame rate is 30 frames per second FPS at 2. The zipScope uses eight white LED lights with two intensity settings to control illumination.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece.
Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular one , binocular two , or trinocular three eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image.
Resolution, also known as resolvant power, refers to the clarity of the image. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities.

You can also do things like 'invert' the image to change a dark-on-light image to a light-on-dark image. I have started a web page with helpful hints on how to use 'mtpaint'. You will typically also rename the file and move it to an appropriate directory. Launching 'guvcview' : To startup 'guvcview' so that it recognizes the USB microscope instead of a web cam or other video device and so that it is ready to take still images rather than video, I made a startup script called 'guvc.
I will describe the script contents in another section below.

You can simply highlight and paste that code into your own script file on your own Linux computer. When one has the script file ready, it is easy to make an icon on your desktop to launch the script which immediately brings up the 'guvcview' control panel window and the viewport window.
The viewport window immediately shows the image that the microscope is capturing. The following images, that show how to make the desktop icon, were captured on an Ubuntu 9. You simply right-click on the Gnome desktop and choose the 'Create Launcher Here is an image of that popup menu. When you choose 'Create Launcher Here is the help that you get for 'guvcview' by entering the command 'guvcview -h' at a command prompt in a terminal window on Linux:. The 'man' help that you get by using the command 'man guvcview' is slightly different from the built-in help. For easy reference, I make that 'man-help' available in this 'man-help' text file.
As a further note on the run-parameters of 'guvcview': I found that the 'guvcview' program saves its default run parameters and changes that you make to them when you use the program in 'rc' run control hidden files in your home directory. For easy reference, here is a sample image of a '.
For completeness, here is a sample image of a '. I see that, in the '.

There does not seem to be such a parameter option via the guvcview command line options. It would be handy to specify something like '-a 0' to indicate that no sound recording is wanted. The initialization messages coming from 'guvcview' indicate that it spends a little processing time, during startup, trying to determine if sound recording should be done.
Here is a sample of 'guvcview' messages from when the program starts up. I use several of the 'guvcview' command-line parameters notably '-d', '-s', '-m', and '-t' to formulate the 'guvcview' command within the launcher script. See the script in the next section. The bottom part of the script, after the 'exit' statement, is simply comment lines to help me remember what I did and what I might want to try in the future.
You can paste this code into your own script file on your PC. Remember to make the script executable. For example: you can use the command chmod guvc. Alternatively, if you are using the Nautilus file manager, you can right-click on the 'guvc. Happy image capturing!

Note the two bright white spots on the right. That is the reflection from 2 of the 8 LED lights surrounding the aperture of the microscope. A grain of salt x. This is 'Sale marino fino' fine sea salt , brand name: 'Masserie di Sant'eramo', from Italy. Note that there is a 'depth of field' effect. That is, the salt crystal is so 'tall' that parts of the crystal at a certain level are in focus, while other levels are out of focus.
