Virtual Microscope Preloader

When working with the online version of the Virtual Microscope you may experience a delay when clicking on a hotspot in the slide to display rotating views under crossed polars and in plane-polarised light. It can be useful to 'pre-load' these rotations as they will appear much more quickly once they are in your browser's cache.

To do this, select the rocks you're interested in using the checkboxes below. An estimate of the total size of the files selected for download is given. You may need to increase the size of your browser's cache if you're pre-loading a lot of files.

Click the Start button to begin pre-loading files. This may take quite a while, so pick a time when you don't require internet access for other purposes! Progress is shown by the progress bar.
