Condition: Used

This Olympus UPlanSApo 4x/0.16 UPLSAPO4X infinity-corrected objective (∞/-/FN26.5) is in good used condition. Part number 1-U2B822, it features RMS threading and is suited to brightfield, fluorescence, DIC, and confocal imaging applications on Olympus UIS2-compatible microscope platforms.

Typically includes:
• Olympus UPLSAPO4X objective lens

The Olympus UPlanSApo (UPLSAPO) series represents Olympus's super apochromat (SApo) class of plan infinity-corrected objectives within the UIS2 optical system. These objectives correct for both spherical and chromatic aberrations and provide high light transmission from the visible to the near-infrared region, achieved through a newly developed multi-layer anti-reflection coating and lead-free optical glass elements that minimise autofluorescence. This makes them particularly well-suited to fluorescence microscopy, live-cell imaging, confocal, and multicolour imaging applications where colour accuracy, flat-field imaging, and maximised signal-to-noise are critical.

The UPLSAPO4X is a dry, infinity-corrected objective designed for use without a coverslip (no coverslip correction), delivering a wide field of view ideal for low-magnification survey imaging, tissue section scanning, colony counting, and high-content screening workflows.
