Semi Plan S100x/1.25 Oil Immersion Objective for BioBlue Microscopes

The Semi Plan S100x/1.25 Oil Immersion Objective is a high‑precision optical component designed specifically for use with BioBlue biological microscopes. Engineered for outstanding clarity and resolution, this objective allows users to observe fine structural detail at 100x magnification, making it essential for advanced biological and microbiological studies.

With its 1.25 numerical aperture (N.A.) and semi‑plan optical design, the lens delivers a flat, sharp image across the field of view while minimising optical distortions. The oil immersion function provides enhanced light‑gathering capability—ideal for studying bacteria, blood cells, and other minute specimens that require maximum resolution.

Manufactured to durable, high‑quality standards, this objective integrates seamlessly into the BioBlue nosepiece system and offers smooth, secure installation for reliable day‑to‑day use in educational and laboratory environments.
