Objective Lenses on the Leica DM4000 Microscope
Leica ACS objective lenses have been designed specifically for SPE confocal microscopes with 405 nm lasers to correct for colour registration errors between the violet and visible lines. They do not have a flat field so Leica recommends that the zoom is set to ≥1.6.
