Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force ...

Versatile, portable, inexpensive and packed with features, the Swift SW200DL Compound Monocular ... but because the microscope came with two eyepiece lenses, magnification could be increased ...

Let's take a look at how to observe cells under a microscope. No prizes for guessing ... Repeat steps 1-5 using the higher power magnification to see the cells in more detail.

Using visible wavelengths of light on the 400 – 700 nanometer (nm) range, the standard array of magnifying lenses in a compound microscope permits sample magnification by up to 1000x.
