Product Overview

The Olympus LUCPLFLN40X2 40× Objective is a high-performance microscope objective designed for applications where magnification, optical quality, and extra working space are all essential. Part of Olympus’s long-working-distance Plan Semi-Apochromat series, this objective delivers detailed, flat-field imaging while accommodating thicker samples or imaging through vessels such as culture dishes or slides.

With 40× magnification and a numerical aperture (NA) of 0.60, this lens strikes a balance between resolution and light gathering, making it well-suited for brightfield, fluorescence, and multi-modal imaging where image fidelity matters. The Plan Semi-Apochromat optical design helps minimize chromatic and spherical aberration, producing sharp, high-contrast images from center to edge — a key advantage for documentation and analysis workflows.

One of the defining features of this objective is its extended working distance (approximately 2.7–4.0 mm), which provides practical space above the specimen for larger sample containers, perfusion chambers, and manipulation tools without sacrificing image quality. This makes the LUCPLFLN40X2 especially useful in both upright and inverted microscope configurations where access to the sample can be restricted.

Additionally, the objective supports a broad spectral range (approximately 340–1300 nm), offering versatility across a variety of imaging modes — from ultraviolet through visible to near-infrared — enhancing compatibility with dye-based and multi-label fluorescence techniques.

Designed with a standard RMS threaded mount, this objective integrates easily into most research-grade upright microscopes, giving laboratories flexibility when building advanced imaging systems.
