Not all microscopes are created equal ... with a laser diode light source, an objective lens, and a photodiode detector behind a pinhole. The detector feeds a homebrew trans-impedance amplifier ...

The fan frame is perfect since it is the right size to slide over the objective lens. If you’re looking for a more capable lighting solution for your microscope, then check out “AZIZ!

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 ...

This diagram illustrates the setup of a Scanning Transmission X-ray Microscopy (STXM) system. An undulator generates a beam of X-rays, which is then focused using a crystal monochromator and a zone ...

When light passes through an aperture, such as the objective lens of a microscope, it undergoes diffraction and spreads out. This diffraction causes the light to form a diffraction pattern, known as ...

Turn the coarse focus so that the stage is as close to the objective lens as possible. You should not look through the microscope to do this. Place the microscope slide – either one you have ...
