This morning we walked around the RIT campus, trying to find a microscope slide to use for our medium-width piece of glass. We first tried to find one in the building where the construct is, but then Dmitry remembered that the guy we were looking for had already graduated, so he was gone. We then tried to borrow one for the engineering building, but they refused to let us, on account of us "being from another college." Luckily we were able to find one in Gosnell Hall, so we brought it back to the lab. I was able to run our program after homing and focusing our setup, and we were pleasantly surprised to find that the resulting surface function was quite similar to that of the function from the thinner glass. It was so similar, in fact, that Dmitry had to take a couple minutes to figure out which was which when I asked him if he could tell.
Unfortunately, our fancy new camera will not be coming for another week, so I won't actually get to use it since presentations are due a week from today. While that is a little disappointing, it's alright, if we make good progress tomorrow, we should be able to take a few images with the Kepler camera, which I'm excited to use.
Tomorrow we'll be fitting curves (most likely Gaussians) to the data I took today. Besides the data from the images with the microscope slide, I also took two more sets of data with no glass cover and with the thin glass (a coverslip) as a second trial where I was much more careful to have our spot of light be in as exact focus as I could manage. Tomorrow we'll compare the two sets of data, and determine the effect of the window thickness and the differences in accuracy of focus.
