12PRACTICE PROBLEM
An engineer is working on an optical communications system and wants to focus a light beam from a semiconductor laser diode (that has a wavelength of λ = 1310 nm) to a specific spot that has a diameter of 50 μm on a photodiode which is located 5.0 cm behind a lens. Determine what has to be the minimum diameter value for this particular lens.
