Axial resolution and numerical aperture, part II
Posted in Tips
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…
Axial resolution vs numerical aperture
Posted in Tips
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…
Wire gauge frequency ratings
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…
Multimeters with IR temp
