With Prime Day coming up on July 8-11, now's the time to get one of the best microscopes for students, essential tools to help budding scientists with their studies.

For cell photomicrography, to reveal the subcellular structures within, we would recommend a compound microscope, with an adjustable lower light source, that can magnify 400x or more.

Most image sensors are made of silicon, which absorbs light over the entire visible spectrum. To manufacture it into RGB image sensors, incoming light must be filtered. Pixels for red contain filters ...

THE light-profile microscope technique, described by Tolansky1, has been adapted by us for the determination of the optical thickness of relatively thick transparent films. A transparent film ...
