iScope IS.7700 – 100x microscope objective, NA 1.25 by Euromex

The iScope IS.7700 is a high‑power oil immersion microscope objective intended for advanced life‑science and education microscopy, offering a compact optical design for high‑resolution imaging.

• High magnification 100x
• Numerical aperture 1.25 for high resolution
• Oil immersion with 0.13 mm working distance
• Compatible with iScope series objectives

Enhanced resolution for demanding analysis

The combination of 100x magnification and a numerical aperture of 1.25 delivers substantially greater light‑gathering capacity than lower‑NA objectives, which translates into finer detail and superior contrast when examining cellular structures or fine material features. In practical terms, a higher numerical aperture reduces diffraction limits, enabling clearer distinction of closely spaced specimen details. This objective therefore benefits users who require reliable high‑resolution imaging for documentation, diagnostics or detailed observation in both teaching and research contexts.

Practical benefits of oil immersion and short working distance

Designed as an oil immersion lens, the objective is optimised to be used with immersion oil to bridge the refractive index between the specimen and the front lens, improving image clarity and resolution. The working distance of 0.13 mm indicates the required separation between the cover slip and the front element; while short, this is typical for high‑NA objectives and results in a compact optical path that enhances resolution. For routine workflows, this specification means refined focusing procedures but considerable gains in image quality when the correct immersion technique is applied.

Seamless fit into established iScope setups

Engineered for the iScope series, the objective integrates into common microscope turret systems and complements standard brightfield and advanced contrast techniques. The SKU IS.7700 identifies the specific optical configuration and simplifies ordering and inventory tracking. Compatibility with established mounting standards and the consistent optical design within the series reduce setup time and ensure predictable performance across instruments used in education labs and life‑science facilities.

Reliable optics and user guidance for best results

Manufactured to precise tolerances, the lens design focuses on delivering repeatable imaging outcomes under normal laboratory conditions. The technical specifications are documented in the accompanying education and life science materials (see source references), which explain handling and cleaning procedures to protect the front element and to maintain optimal performance. For users new to high‑NA oil objectives, following recommended immersion practices and routine optical checks will preserve image fidelity and prolong service life.

FAQ

What working distance does this objective require?
The working distance for the iScope IS.7700 is 0.13 mm, which is typical for high‑NA oil immersion objectives and requires correct immersion technique to achieve optimal focus.

Is this objective suitable for life‑science applications?
Yes. The combination of 100x magnification and a numerical aperture of 1.25 makes the objective well suited to life‑science microscopy where fine structural resolution is required.

What does numerical aperture 1.25 mean in practice?
A numerical aperture of 1.25 indicates strong light‑gathering ability and a correspondingly improved resolving power; when used with immersion oil, it enables sharper, higher‑contrast images than lower‑NA lenses.

Which product code should be used when ordering?
Use the SKU IS.7700 to ensure the correct Euromex 100x oil immersion microscope objective is supplied.
