The aplanoXX_NA0.8 objective has a protective window for diffraction-limited focusing. With a numerical aperture up to 0.8 inside transparent materials, it compensates for spherical aberration at depths ranging from 0 to 4 mm. It is optimized for high-power ultrafast lasers with wavelengths of 515, 800, and 1030 nm.
