The Olympus UPlanSApo (UPLSAPO) series represents Olympus's super apochromat objective range, engineered for the UIS2 optical system. Super apochromat correction compensates for both spherical and chromatic aberrations simultaneously, delivering outstanding colour fidelity and resolution across the visible spectrum into the near-infrared region. These objectives are optimised for demanding life science applications including fluorescence, UV fluorescence, and transmitted brightfield microscopy.

The UPLSAPO4X is designed for use with Olympus BX and IX series research microscopes and is compatible with BX40, BX41, BX43, BX45, BX50, BX51, BX53, BX61, and BX63 model families.
