Shopping for a digital USB microscope that works on Mac OSX? It isn't just webcams that have adopted the USB Video Class camera standard. There's now a decent range of UVC digital computer microscopes and inspection scopes that are UVC compliant and compatible with any modern OS : MacOS, Linux, and Windows.

Omax HD UVC Digital Microscope

Optical & Digital Imaging

The Go-To brand seems to be Amscope with good software support for Macintosh computers. Omax is another digital USB scope manufacturer worth checking out. Some are conventional computer lab microscopes for medical or biological uses that combine both optical eye-pieces plus a digital camera sensor for capturing and recording whatever it sees under high magnification. Windows users will likely find snapshot and video capture apps more readily available, but Linux and Mac OS users will find any general purpose still image or video capture program will let them capture images or video clips from the digital computer microscope's sensor.
