It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Figure 1 (a) Structure of the mesoscopic objective, (b) Aberration distribution of the mesoscopic objective, (c) Wide-field imaging system built with the mesoscopic objective, (d) Laser point-scanning ...

A British nanotech invention has revolutionized the humble optical microscope by quadrupling its magnification power to a level far beyond what could previously be achieved with visible light. The new ...

Over on YouTube [Applied Science] shows us how to make an f/0.38 camera lens using an oil immersion microscope objective. The f-number of a lens indicates how well it will perform in low-light. To ...
