Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...

A team of scientists in the lab of Changhuei Yang at Caltech has developed an inexpensive, robust method for autofocusing microscopes that involves little more than a couple of LED lights and some ...

Owning a Microscope is great fun as a hobby in general, but for hackers, it is a particularly useful instrument for assembly and inspection, now that we are building hardware with “grain of sand” ...

Question from Nora in Ms. Fitzpatrick’s class. A microscope is an instrument that lets you magnify and see really small things that you cannot distinguish with your naked eye. The earliest microscopes ...
