Ever since the invention of the first compound microscope by Zacharias Jansen in 1590, our understanding of the microscopic world has grown exponentially. Microscopes have evolved from mere assemblies of magnifying lenses to extremely powerful tools for visualization on the atomic scale. You can find a wealth of information on the workings of a microscope…

Calculate the transmission and transmitted power of a Gaussian beam passing through a circular aperture.

Dichroic Mirror/Filter This is a semi-reflective filter which can also be referred to as ‘dichromatic beam splitter’. Unlike the Longpass filters which absorb light which is not transmitted (see Part 1 of the Glossary), these filters reflect light at lower wavelengths and transmit light at wavelengths above the ‘cut-on’ wavelength. As beam splitters, they are…

I recently introduced you to the concept of polarising microscopy. Naturally, if evaluating refractile material is an everyday part of your research, it is definitely worth investing in a professional polariser modification for your microscope. But if you only use a polariser occasionally, this might not be the best use of your lab’s money. In…

The resolution of any microscope is related to the numerical aperture of the lens and the wavelength of light used to form the image, and can be calculated using Abbe’s law. This, however, is the ideal situation – the best case scenario. In real life, resolution must be defined in terms of contrast, and there…
