A long time ago in a lab about 20 miles away, I was working for a company called Mediwatch to develop a new micro-array platform that was internally named Zero-flow. It was a nifty little device that was excellent at controlling the flow of a sample over a sensor system. The company I worked for at the time was small and not flush with cash. So for a while the only resources allocated to the design and development of this technology was me. With this budget of £0 I needed to produce an assay system that could demonstrate sensitivity significant Continue reading

Brewster angle Lego microscope

Lego BAM

Brewster’s angle is the angle at which light of a certain polarisation won’t reflect off a surface. The resulting reflection will then be made up of only light from a single polarisation (p-polarised). This little optical quirk is how polarised lenses remove lots of scattered reflections in photographs and why polarised sunglasses are so much better when lounging by the seaside. However, rather than just being something that makes sunny days even better, it also provides a neat trick for visualising things that would otherwise be invisible to other analytical methods. Brewster’s angle for water is approximately 53.1°, which is calculated Continue reading
