Additional information about NA recovery can be found in other NA literature If we find that any of the terms used in this book are unfamiliar we should feel free to make use of a dictionary These guides are meant to be used by NA members at any stage of recovery whether it's our first time through the steps or we've been living |
What does na mean in microscopy?
In microscopy, NA generally refers to object-space NA unless otherwise noted. In microscopy, NA is important because it indicates the resolving powerof a lens. The size of the finest detail that can be resolved (the resolution) is proportional to ?/2NA, where ?is the wavelengthof the light.
What does na mean in fiber refraction?
In particular, manufacturers often quote "NA" for single-mode fiberbased on this formula, even though the acceptance angle for single-mode fiber is quite different and cannot be determined from the indices of refraction alone. The number of bound modes, the mode volume, is related to the normalized frequencyand thus to the NA.
How does the number of bound modes affect the Na?
The number of bound modes, the mode volume, is related to the normalized frequencyand thus to the NA. In multimode fibers, the term equilibrium numerical apertureis sometimes used. This refers to the numerical aperture with respect to the extreme exit angle of a rayemerging from a fiber in which equilibrium mode distributionhas been established.
How much does na cost?
There are no dues, fees, or any other requirements other than to seek recovery from addiction to drugs. NA is a nonprofit program of recovery that is not connected to any other twelve-step fellowship or treatment programs, and has no religious affiliations.
