Scientific papers are difficult to read because they are written to be precise, correct, and rigorous. Being accessible is only a "nice to have". So why not make a second version that is much more understandable? Maybe even in a video format? Here you go:
Microscopy with a tilt
This is the recording of a Euro-Bioimaging webinar. It provides an overview of the advanced microscopy technologies aimed at improving 3D imaging that we have been developing in our lab and together with collaborators at the European Molecular Biology Laboratory in Heidelberg. Two methods are presented in detail, SOLIS and OPM, but the talk also covers the principles of rolling shutter line scanning, which minimizes out-of-focus light, and axial sweeping in lightsheet microscopy, which enhances resolution.
Multifocus Gratings - Principle and Production
Recording more than one focal plane simultaneously is a great time saver for 3D imaging. In this video, we'll have a closer look at the physics of multifocus imaging with warped gratings and explore how to make them yourself from scratch (no cleanroom required!).
Instant Volume Microscopy (aka SOLIS)
Remember Avatar, the first 3D movie? Yeah, that wasn't 3D. Actual 3D needs more than polarising glasses. We have now developed a real 3D imaging system that allows recording of entire scenes in 3D in single camera exposures. Watch the short explainer video to get an overview or dive deeper into the technology by watching the recording of a Scientific talk, given at the ELMI meeting in Finland in 2022 on the topic.
Label-free superior contrast with c-band ultraviolet extinction microscopy
With a resolution down to 215 nm, we are, for the first time in a far-field label-free method, able to image individual fenestrations within their sieve plates of liver sinusoidal endothelial cells. This is possible through the supreme contrast and high resolution thanks to the special properties provided by complex phase microscopy in the deep ultraviolet C-band region.
Vectorial Jones calculus
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”
Forskningsdagene ("The Research Days") is a national, annual festival under the auspices of the Research Council of Norway which has been held since 1994. The motto for the festival is "Room for big thoughts", and during the festival, researchers from all over Norway go out among people to demonstrate research in practice. Due to the 2020 pandemic, the festival was all-digital. Watch our contribution: a virtual lab visit!

Have you ever been to a laser lab?
So many pieces of glass and they all serve a purpose (ideally): beam steering, focusing, collimating, expanding, polarising, shearing, combining, converting, filtering, ...
In this video series, I go over the basics that will help you with the hands-on work of your own optics research.
