New paper on vectorial Jones calculus: Donut or not, that is the question!

posted in: News, Research | 0

Take an image of a single fluorophore with a microscope. When the fluorophore is pointing just the right way, you will see a donut on the camera. Surprising, right? But that’s not even always the case. With some lenses, the donut is completely invisible due to a bright central spot of light. Find out how to calculate such things (free software available) and when to expect a donut (or not) in our new work on “Quantification of the NA dependent change of shape in the image formation of a z-polarized fluorescent molecule using vectorial diffraction simulations”.
