High numerical aperture for maximum resolution

The combination of 100x magnification and a numerical aperture of 1.25 places this objective among specialist high‑resolution optics. Numerical aperture describes the light‑gathering ability of the lens: a higher value permits finer detail and improved contrast when imaging sub‑micrometre structures. For routine laboratory tasks that require clear visualisation of cell morphology or histological detail, this optical specification reduces the need for aggressive digital enlargement and supports accurate interpretation of sample structure. The lens design emphasises image fidelity across the field, making it suitable for documentation and analysis workflows where optical clarity is paramount.

Design features that support precise sample handling

The objective’s 0.36 mm working distance defines the gap between the lens front and the cover glass when in focus. A short working distance is typical for oil‑immersion optics and allows effective numerical aperture utilisation; however, it requires careful stage movement and attention to immersion technique. The PLi oil‑immersion construction achieves a refractive index match between glass and lens, enhancing resolving power. Routine handling involves applying a drop of immersion oil and avoiding abrupt vertical movements; cleaning after use preserves the optical coatings and prevents deterioration of image quality. These characteristics support consistent, repeatable imaging when integrated into standard laboratory procedures.

Suited to life‑science education and detailed research tasks

The optical parameters suit applications in biological microscopy, teaching laboratories and any setting where resolving power is critical. The objective performs well for high‑magnification observation of fine cellular features and thin tissue sections, providing a visual advantage for tasks such as differential staining assessment or microorganism inspection. Its specification is documented in educational and life‑science literature, emphasising relevance for curricula and research where dependable optical performance is required. The combination of design and specification supports efficient workflows and reliable imaging outcomes.

Practical maintenance and assurance of long‑term performance

Careful maintenance preserves the objective’s performance: using recommended immersion oils, cleaning lens surfaces with appropriate optical wipes and minimising exposure to contaminants will retain contrast and resolution. The construction is intended for routine laboratory usage; adherence to correct immersion technique prevents damage associated with contact between objective and specimen. For users who require confirmation of suitability for a given microscope stand or application, consult the technical documentation referenced in the product literature for compatibility notes and application examples.
