How to Build a Multipurpose Microscope Stage for Gems
by Dr. Raul Berenguel, PhD.
Figure 1: A multipurpose microscope stage for gems.
"When observing gemstones through a microscope, we gemologists normally use gemological tweezers or a stone holder. We can attach these tweezers to the microscope itself or to an external support.
It’s important to use tweezers instead of fingers to keep dirt, oil, and fingerprints off the gem. Unfortunately, the tweezers also make minor movements and adjustments to viewing angles difficult or limited. Since gemologists have to move the tweezers by hand under magnification, the images jump abruptly. Furthermore, the small button of the tweezers doesn’t allow for soft movements, which makes rotating the gem no easy task.
To address this problem, I’ve created a multipurpose microscope stage for gems that you can build yourself. You can see the finished instrument in Figure 1 at the top of this article. The video below shows how the stage moves and works.
