Pinholes and pinheads! Before getting to the latest installment of the Calibration Campaign, I want to remind everyone that I welcome questions and comments (unless you are a troll!). Happy to answer. Also do hit the subscribe button so you…

Last week, I wrote about my misgivings over the 5 degrees of separation (actually, of misalignment) between the rotatable polarizer’s positioning on the microscope stage and the polarization of the microscope’s laser. In discussing with Rudolf Oldenbourg (MBL), I learned…
Five degrees of separation
Last week, I carried on the quest for calibration. Avalon remains stubbornly out of reach. I tried things I mentioned last week and a new thing besides. The liquid crystal device seems undamaged. To have a look, I improvised a…
Calibration continuation
Last week, I had three sessions on the confocal to work on calibration. My calibration went from steaming garbage to cold leftover pizza (Fig. 1). Better, but not yet appetizing. What you are looking at in Figure 1 is the…
Calibration consternation
I can think of stronger words: mutilation? defenestration? OK, OK. I was not injured let alone thrown out of a window. This past week, for the first time, I tried to calibrate the system. What system? The one I brought…
