Olympus UPLANAPO 100x HR TIRF Plan Apochromat Oil Immersion Objective

The Olympus UPLAPO 100× HR TIRF is a landmark objective in the Olympus lineup — one of the first plan-corrected apochromat objectives to achieve NA 1.50 with standard oil immersion, setting a new benchmark for evanescent field confinement and resolution in TIRF microscopy. At NA 1.50, the evanescent field penetration depth in TIRF is minimized to its theoretical limit, providing the tightest possible optical sectioning at the coverslip surface for single-molecule detection, membrane dynamics, and receptor-ligand interaction studies where background fluorescence from out-of-focus molecules must be completely eliminated. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across all fluorescence channels — essential for multi-color TIRF co-localization, PALM, STORM, and dSTORM super-resolution workflows where chromatic shift between channels would compromise localization accuracy. The high NA also maximizes photon collection efficiency, directly improving signal-to-noise ratio for single-molecule detection and enabling shorter exposure times in live-cell single-molecule tracking experiments. Compatible with Olympus BX, CX, and IX series microscopes. Supplied new from stock, part number N5701700.
