To recap the previous post on axial resolution and numerical aperture in two-photon microscopy:
For excitation deep in scattering tissue, higher NA can actually be detrimental because the light cone…
Recently, microscope manufacturers have been releasing ever higher NA objectives for multiphoton imaging. Although higher NA objectives should give better axial resolution, they might not be ideal for imaging deep into…
As previously noted, homemade cables are to be avoided. However, stock cables are not always up to spec. For example, if one wants to drive stepper motors using a…
I thought I needed a $30 multimeter. But then I saw that for just a few bucks more I could get some more features. This process repeated itself until I ended up buying …
Thanks go to commenter ybot for this one. They pointed out this handy iPhone-to-Microscope mount iPhone case.
From the pictures, it looks like the prototype was printed on a Makerbot, which isn’t terribly…
CircuitLab is an online circuit design tool. This is my new favorite way to jot down circuits. The interface is clean and simple and even has some test/simulation facilities. It also has a…
By virtue of their small eyes, mice enjoy a large depth of field. In a classic experiment (buried in the methods section) Balkema and Pinto put +6, 0, and -7 diopter lenses in…
This is an iOS/iPhone app that uses the camera to optically recognize resistor color code bands. I find this interesting because I tried writing something like this one time. I couldn’t sleep at 3am…
