iScope IS.7200-I microscope objective — 100x oil, NA 1.25 (Euromex)

iScope IS.7200-I is a 100x oil immersion objective with NA 1.25 and a 0.13 mm working distance, optimised for high-contrast imaging and compatible with darkfield methods

• 100x oil immersion objective
• Numerical aperture 1.25 for high resolution
• Built-in iris diaphragm for contrast control
• Optimised for darkfield and high-contrast imaging

Achieve the highest detail with oil immersion performance

The optical design of this objective combines a 100x magnification with a numerical aperture of 1.25, which increases both resolving power and light collection. Used with immersion oil, the lens minimises refraction at the sample interface so that fine structural details become visible that would otherwise remain unresolved. For routine work that demands visual clarity—such as cell morphology, fine structure inspection or materials microstructure—the high NA is the decisive factor for sharper images and improved signal-to-noise. The built-in diaphragm allows precise tuning of contrast without extra accessories, maintaining a compact optical path.

Controlled contrast and compatibility with specialised techniques

A short working distance (WD 0.13 mm) requires careful handling but enables proximity to the specimen for maximum resolution. The objective features a built-in iris diaphragm, permitting immediate control of aperture and depth of field to balance contrast and sharpness during observation. According to the manufacturer’s specification, the lens is described as Super Contrast PLi oil objective and is expressly noted as suitable for darkfield contrast, making it a reliable choice when contrast-enhancing illumination is required. These properties make the lens versatile across brightfield and darkfield setups while keeping alignment and adjustment straightforward.

Reliable optics for laboratory and quality-control environments

Engineered by Euromex as part of the iScope series, the lens is intended for precision tasks where image fidelity is essential. The solid optical specification supports reproducible results in both research and industrial inspection settings. Choosing an objective with these characteristics reduces time spent optimising illumination and focus, which in turn streamlines workflows and raises throughput in microscopy tasks. For laboratories seeking consistent, demonstrable improvements in image detail, this objective’s combination of oil immersion, high numerical aperture and integrated contrast control represents a practical performance upgrade.

FAQ

What is the magnification and numerical aperture of this objective?
The iScope IS.7200-I is specified as a 100x objective with a numerical aperture of 1.25, offering high resolving power for fine-detail work.

Is this objective suitable for darkfield microscopy?
Yes. The optical data indicate the lens is suitable for darkfield contrast, and its Super Contrast PLi design supports enhanced contrast techniques.

Does the objective require immersion oil, and what does that mean for use?
This is an oil immersion objective; immersion oil must be used between the cover slip and the lens to achieve the specified numerical aperture and optimal resolution, and care is required due to the short working distance.

What is the working distance and how does it affect handling?
The working distance is 0.13 mm (WD 0.13 mm), which positions the front lens very close to the specimen—this maximises resolution but necessitates careful focusing and sample preparation.

Which manufacturer and SKU identify this lens?
The objective is manufactured by Euromex, product designation iScope IS.7200-I, SKU IS.7200-I.
