Show more cards here -
Numerical aperture of an objective is...A measure of its ability to gather light and to resolve detail in a specimen.
-
High N.A.
Lenses ... (2)1. Collect more light and formbrighter images
2. Allow to see more detail -
Formula N.A.NA = sin mu
-
Maximal and best lenses N.A.Maximal = 1, Best = 0.95
-
Mu increases when... (2)1. The aperture of the lens is larger
2. Distance to the sample is minimized -
Image brightness formulaNA^2
