Hi all,
Would someone please explain the primary differences between Nikon's Lambda series and VC series of Plan Apochromat objectives?

From their website, I understand that the Lambda series objectives have better transmission towards the red end of the spectrum than the VC series objectives. Are there any relative advantages of the VC series?

Thanks!
Kyle

Hi Kyle,

As i understand it the Lambda series lenses only have axial chromatic  
correction down to 435nm whereas the VC (Violet Corrected) have  
chromatic correction down to 405nm.  As you say i think the overall  
transmission across the spectrum is better in the lambda series.

There may well be other differences.

Regards,

Matt

Hi Kyle,

The main difference is in the range of the chromatic aberration corrections. Chromatic aberration is the inability of a lens to focus light of different wavelengths to the same convergence point.
The Lambda series is corrected for blue to far red range 435-850nm while the VC (violet corrected) series corrects from UV to red 405-656nm.

I have used the Lambda series 25x 1.1 NA with 375nm excitation and it
actually worked fairly well.  The same lens also works for two-photon all
the way out to 1000 or so as well, as we do two-photon on the same system
(A1) with a Chameleon.

Kyle,

The Nikon VC lens will be chromatically corrected at the Violet end (Violet Corrected), we have one on our EC1 confocal and it seems to do what it claims, I don't know how it compares with the lambda lenses,

yours
