Occasionally I use this microscope to get close-up pictures of nibs, and sometimes LCD panels.

The microscope behaves just a like a webcam. You can use your computer's built in camera to see the image it produces.
Optionally, you can install the Plugable Digital Viewer App which provides some additional features.
