iScope IS.7100 – Microscope objective, 100x, NA 1.25 (Euromex)

iScope IS.7100 is a 100x oil immersion microscope objective optimised for high-resolution observation in life science and educational settings.

• 100x oil immersion magnification
• Numerical aperture 1.25 for resolution
• Very short working distance 0.13 mm
• S100x/1.25 EPL oil objective design

Exceptional detail with a high-aperture 100x optic

The 100x oil immersion configuration delivers markedly higher resolving power than dry objectives at the same magnification. With a numerical aperture of 1.25, the lens admits more light and resolves finer structural detail, which is crucial for tasks requiring clear visualisation of cellular structures and sub-cellular features. The combination of high NA and oil immersion translates into improved contrast and image fidelity, enabling reliable interpretation of specimens in both teaching and routine laboratory workflows.

Optimised for demanding biological and educational use

Designed as an S100x/1.25 EPL oil objective, this optic is suited to applications that demand top-tier resolution rather than long working distances. The 0.13 mm working distance indicates very close proximity to the coverslip, a trade-off that yields superior image sharpness at high magnifications. For practical purposes, this objective is most effective with prepared slides and thin specimens where immersion oil can be applied safely; the optical design supports detailed observation necessary in histology, cytology and advanced instructional microscopy.

Practical handling, compatibility and verification

The short working distance and oil immersion requirement call for careful handling during routine use and cleaning to maintain long-term performance. The specification set is documented in the manufacturer’s technical literature (Education PDF; Life Science PDF), which lists the S100x/1.25 EPL oil objective designation and confirms the optical values. For system integration, the lens is intended for standard microscope setups that accept oil immersion objectives; for precise compatibility with a specific nosepiece or condenser arrangement, refer to the instrument documentation or contact the supplier to verify mechanical and optical match.

FAQ

Is the iScope IS.7100 an oil immersion objective?
Yes. The iScope IS.7100 is specified as an S100x/1.25 EPL oil objective, requiring immersion oil for optimal optical performance.

What specimens are typically examined with this objective?
Typical uses for this objective include high-resolution observation of prepared biological samples, stained tissue sections and detailed cell morphology studies where the high numerical aperture and oil immersion provide improved resolution.

How should the lens be cleaned after use with immersion oil?
After use, gently remove excess oil with appropriate lens tissue and a solvent recommended for optical cleaning; avoid abrasive materials and store the objective in a dust-free environment to preserve the optical surfaces of the IS.7100.

Will this objective fit standard microscope nosepieces?
The IS.7100 is designed for standard microscope systems that accept oil immersion objectives; for confirmation of mechanical compatibility with a specific instrument, check the system documentation or consult the supplier.

What does the numerical aperture of 1.25 mean for image quality?
A numerical aperture of 1.25 indicates a high light-gathering capacity, which improves resolution and image brightness at the 100x magnification, allowing finer structural details to be distinguished than with lower-NA objectives.
