Dear All,

 

Immersion lens, especially high NA ones:  Although not simple to setup, the
most accurate way to measure transmittance/power is to use two objectives
focused on a coverslip sandwich.   The position in XY&Z can be tweaked to
give the maximum power.  Infinity corrected lens this is easier.  I would be
happy to provide more details off line.

 

Happy imaging

 

Rich
