Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Appropriate magnification necessary possibly determined to be greater than 63x
Analytic risk reduction of lenses gives validity to continue on to physical risk reduction tests
Accomplishments from Previous Week
During finals week we were finishing up our risk analysis on our microscope. Through it, we found that we could buy appropriate lenses to make a microscope within the specified dimensions
Further steps will be taken to fabricate risk reduction test rig for shorter tube lengths
Possibility of sticking to standard tube lengths might be taken into consideration

The microscope itself isn't "too" bad, but the bracket is not the best designed. They use slots to place the position of the microscope depending on the model, but when I tried mounting it, it was definitely challenging. If we can figure out a way to make it better, and still be able to use the same bracket for all of them, then it would be a huge plus.
Microscope functionality wise was not bad at all, though it was pretty dense and heavy. I think the largest weight source is the slider that adjusted focus, because it seemed like it was made from steel or something. I'm not entirely sure, but that's something we might want to consider improving.
The pinholes are VERY hard to see when the lasers are on. I couldn't see the pinholes at all, until Paul shined a LED through the fiber optic, so I think we should raise the priority of having those LED filters because they help a lot.
63X magnification is good enough to view all of the lasers at once, but isn't magnified enough to be able to look at close detail at one. We might want to discuss increasing the magnification and seeing if that would help with alignment.
Depending on the lasers, it was difficult to see the actual beam. On the Canto, I was able to see the lasers fine because there was no yellow-green laser, but for the Aria, it was hard to see the beam. In terms of aligning the lasers, it seems that the orientation can vary in the angle, and to and from the pinhole, which will be harder to detect via software.

Goals for Next Week (list names after each item). Use specific and measurable objectives.
Find,Choose, and Purchase Lenses for risk reduction tests (Kevin)
Purchase webcam or use existing camera to perform risk reduction tests for camera software (Justin)
Continue Camera research and selection, additional focus on LED back light filters (Carlos)
Design prototype for mounting bracket and focus adjustment mechanism (Daniel)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Perhaps consider making a lighting system where the pinholes can be back lit to allow for better contrast with the lasers
We will be looking into moving this up on the priority list and seeing how possible it is to accomplish this
