Always something new when you run a core facility…
There’s a lab on my campus that works with CCD chips
to make cameras for big telescopes. Since they do their own backthinning,
they want to inspect the chips. They approached me about doing reflection
mode confocal. The person I’m working with has a degree in optics,
which has made the training easy. My problem is that I’m a
biologist, not a materials science person, and other than some quick
instructions on how to set up the Zeiss LSM 510 for reflection mode, I really
feel at a loss.
We did some imaging today and I’m not sure how to
interpret what we’re seeing. What should be slight
“bumps” look more like “pits”. Also, I’m
seeing what looks like (for lack of a correct technical term) linear diffraction
from the chip surface. In fact, when you looked at some of our
“pits” from the side, they looked a lot like the top half of a PSF.
Is there anyone out there with some experience with this
type of sample that could give me a few pointers? If there’s a
review article you can refer me to, that would be great too.
Thanks. Enjoy Pi Day tomorrow (3.14)!
