Long Working Distance "LD" version. This is different from the one that is not LD. They look about the same, so don't confuse them. These LD C-APO lenses are special with confocal (and even wide-field fluorescence) because you can image deeper into the tissue because of the long working distance. That gives you the ability to do the z-stacks and create 3-D.And they are rated for IR which is best for penetration. 63x / 1.15, Water, ∞/0.14-0.19. Korr UV-VIS-IR. FWD=0.60mm at CG=0.17mm.
