To use a light microscope to examine animal or plant cells. To make observations and draw scale diagrams of cells. Turn the coarse focus so that the stage is as close to the objective lens as possible ...

For example, using green light with a wavelength of 550 nm and an objective with a typical NA of 0.7, a standard light microscope can resolve features down to a limit of 0.61 × (550 nm)/0.7 ≈ 480 nm, ...

Constructed with an LCD digital display, multiple lenses and XY stage plate navigation, the Celestron PentaView feels professional, enables specimens to be viewed by a large audience and is an ...

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Grab your lab coat, or at least pretend you have one, and prepare to zoom way, way in because we’re about to explore a world ...

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 ...
