Hello everyone, I hope you’re all doing well during this difficult time. As I mentioned before, I’m no longer able to work in the lab at George Mason University. Additionally, given the severity of the current COVID-19 situation, I’m unable to work with my lab partner at home either. However, I’m still trying to get things done. More specifically, I’ve been looking into the physical experiment set-up I was supposed to work with. For instance, I recently researched how to create a laser sheet that would pass through a well in a Transwell plate. I discovered that all I would need to do this would be a laser source, a polarizer, and some lenses. To create a rectangular sheet of coherent light, I would have to create a “beam expander” using a converging and diverging lens. In specific, there would have to be a plano-concave cylindrical lens in series with a plano-convex cylindrical lens. The polarizer would most likely be placed before the lenses in order to orient the light waves horizontally. Over the coming weeks, I hope to further look into the experimental set-up my GMU professor was working with. I wish everyone all the best and stay safe!
