M Plan SemiApochromat

MPLFLN series

Plan SemiApochromat objective lenses, giving high-level correction for chromatic aberration. The lineup consists of 7 objective
lenses ranging from 1.25x to 100x, and secures a W.D. of 1mm or longer. Since the exit pupil position of the 5x-100x objective
lenses is standardized, the position of the DIC prism does not have to be switched when changing the magnification.
For ultra low magnifications (1.25x, 2.5x), use together with analyzer and polarizer of the reflected light illuminator.
