WitrynaYes the lens can output this high NA, but it won't be meaningful for imaging because the aberration performance will be crap in this case. You also need to be very careful of NA measurements with lasers because they output Gaussian beams whereas manufacturers generally talk about their specifications with a uniformly apodised beam.

Witryna4 lip 2024 · Dear all I have a very basic question about objective lenses with NA larger than ~1.4: can for instance a 1.49 NA lens gather more light than a 1.4 (1.33 to 1.38) NA lens from a biological sample?
