iScope IS.7140 microscope objective — 40x, NA 0.65 (Euromex)

A compact iScope IS.7140 microscope objective engineered for routine microscopy tasks and educational use, offering high-resolution imaging with a short working distance for close specimen inspection.

• 40x magnification for detailed observation
• 0.45 mm working distance for close-up imaging
• Numerical aperture 0.65 for improved resolution
• Euromex quality; model IS.7140

Enhanced resolution and image contrast for routine inspection

The 40x magnification combined with a numerical aperture of 0.65 delivers noticeably higher resolving power compared with lower-NA objectives, making fine structural details easier to discern during material inspections or biological observations. In practical terms, a larger numerical aperture permits the objective to collect more light and resolve smaller features; this translates into clearer, sharper images on the eyepiece or camera, improving throughput where accurate visual assessment matters. The construction emphasises optical performance while remaining suitable for everyday laboratory and teaching environments.

Close working distance tailored to precise sample handling

A 0.45 mm working distance indicates that the lens must be positioned close to the specimen to achieve focus; this design is ideal for thin preparations and high-detail work where proximity to the sample enhances contrast and clarity. For users new to the term: working distance is the physical gap between the objective front lens and the specimen surface when the image is in focus. A short working distance requires careful stage control but rewards with better light collection and finer apparent detail, which benefits inspection tasks that prioritise visual accuracy over deep-field clearance.

Compatibility and application in microscopy setups

Designed as a microscope objective for standard microscope optical trains, the lens is categorised for use with microscopes and integrates into educational and routine laboratory workflows. The specification S40x/0.65 EPL (as referenced in technical documentation) indicates an objective optimised for efficient imaging under common brightfield conditions. The technical profile supports faster evaluation cycles and consistent image quality, making the component a pragmatic choice for laboratories that balance performance with straightforward operation.

Practical handling, maintenance and operational tips

Due to the short working distance and optical precision, careful handling is advised when changing or positioning the objective. Regular cleaning of external optics with appropriate lens tissue and solvent preserves image quality; avoid contact with the lens surface and ensure the stage is stable before lowering the objective. For users who require assistance interpreting the numerical data or integrating the objective into an optical system, technical documentation and reference notes are available that explain the values and their practical implications for everyday microscopy tasks.

FAQ

What magnification does this objective provide?
The Euromex IS.7140 objective provides 40x magnification, suitable for detailed observation in routine microscopy.

What does a numerical aperture of 0.65 mean for image quality?
A numerical aperture of 0.65 indicates improved light-gathering and resolving capability; the IS.7140 objective benefits from sharper detail and better contrast compared with lower-NA lenses.

Is the short working distance a limitation for all samples?
A 0.45 mm working distance requires careful stage control and is best suited to thin or low-profile samples rather than thick specimens that need more clearance.

Can this objective be used in teaching laboratories?
Yes. The optical characteristics of the IS.7140 make it well suited for educational settings where clear resolution of structure and repeatable results are important.

Where can technical documentation for the objective be found?
Reference data such as "S40x/0.65 EPL objective" and further specifications are noted in the product PDFs cited in the technical documentation.
