One of the laser-scanning microscope's primary advantages over optical ones is that the latter maxes out at 1,500 times magnification, as noted by Gizmodo. Doctor Volt says they aren't sure of the ...

TEMs have a maximum magnification of around ×1 000 000, but images can be enlarged beyond that photographically. The limit of resolution of the transmission electron microscope is now less than 1 nm.

Designed by German YouTuber Doctor Volt, a recent DIY project uses parts of a defective Samsung BD-J5900 Blu-ray player to put a laser-scanning microscope together.
