Olympus PlanApo 60x/1.40 Oil Immersion Objective (NA 1.40, Infinity, RMS)

The Olympus PlanApo 60×/1.40 Oil is one of the most capable objectives in the Olympus biological lineup — a benchmark plan apochromat objective combining the maximum oil immersion NA of 1.40 with Olympus’s highest-level chromatic and spherical aberration correction. At NA 1.40, this objective delivers the maximum resolution and fluorescence light collection available in oil immersion microscopy, making it the definitive choice for TIRF, single-molecule, and super-resolution imaging where maximizing photon collection from the evanescent field or individual fluorophores is critical for signal-to-noise ratio. The plan apochromat correction ensures accurate chromatic registration across all fluorescence channels — essential for multi-color co-localization, FRET, and any imaging workflow where chromatic shift between channels would compromise data integrity. The 60× magnification provides the ideal combination of high magnification and field of view for single-cell and subcellular imaging on Olympus systems. This is the legacy RMS thread version (SKU PLAPO60XO), compatible with Olympus BX, CX, and IX series microscopes with RMS nosepieces. This unit is offered in excellent condition with flawless optics at a significant discount to the list price of $5,900. SKU PLAPO60XO.
