The two-channel N7747A and four-channel N7748A optical power meters from Agilent Technologies bring the industry-leading sensitivity of the 81634B sensor module to the compact multichannel N77 ...

Optogenetics continues to be one of the easiest ways to directly and quickly manipulate the behavior of cells, and the lasers necessary to employ this method are often inexpensive and easy to find.

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.
