Infinite flat-field compound achromatic objective lens
SOPTOP UPlanAPO series of flat-field compound achromatic universal objective lenses, by correcting the axial chromatic aberration of red, green and blue light, make them converge to the same focal plane at the same time, and effectively correct the axial chromatic aberration of violet light, and realistically reproduce the colors of the observed objects, such as red, green and blue. Extra-large numerical aperture further improves the resolution and effective magnification.
