iScope IS.8840 — Euromex 40x microscope objective, NA 0.65, WD 0.43 mm

The iScope IS.8840 is a 40x microscope objective designed for high-resolution imaging in education and life-science microscopy, providing a balance of detail and light-gathering for bright-field applications.

• 40x high-power magnification
• Numerical aperture 0.65 for high resolution
• Short working distance 0.43 mm
• Compatible with iScope series objectives

Capture finer detail with a high numerical aperture

With 40x magnification paired to a 0.65 numerical aperture, this objective is tailored to deliver high resolution and improved contrast for small structural details. The numerical aperture expresses the lens's light-gathering ability and directly affects the achievable resolving power; a 0.65 NA therefore supports sharper images and more reliable differentiation of adjacent features. For laboratory managers and instructors, this means clearer visual results on cellular and tissue specimens without resorting to excessive digital enhancement.

Optimised for demanding focus positions and delicate samples

The 0.43 mm working distance reflects the optical design prioritising numerical aperture and resolution. A short working distance benefits high-NA performance by positioning the front lens close to the specimen, which enhances detail capture in thin preparations. This configuration is suitable for typical slide-based samples and requires careful stage and condenser alignment. The objective follows the S40x/0.65 EPLi specification and integrates into the iScope series, enabling straightforward replacement or upgrade within compatible Euromex setups while maintaining optical consistency across a microscope fleet.

Practical integration for teaching and life-science workflows

Engineered for microscopes used in education and routine life-science tasks, this objective combines precise optics with robust manufacturing to support frequent handling and repeated use. The lens specification is documented in manufacturer materials (see Education PDF S.24; Life Science PDF S.16,41), allowing procurement and technical teams to verify compatibility and imaging expectations before purchase. For facilities consolidating suppliers, the objective provides predictable performance for lab benches, training rooms or multi-user microscopes, reducing downtime and simplifying standardisation across instruments.

FAQ

What magnification does this objective provide?
The iScope IS.8840 provides 40x magnification, designed to reveal fine structural detail in standard slide preparations.

How does the numerical aperture influence image quality?
A 0.65 numerical aperture increases light-gathering and resolving power; the iScope IS.8840 benefits from this by delivering clearer, higher-contrast images compared with lower-NA objectives.

Is the 0.43 mm working distance suitable for routine slides?
The 0.43 mm working distance supports high-NA imaging but requires careful specimen preparation and stage adjustment; thin coverslips and precise focusing are recommended for optimal results with the iScope IS.8840.

Which microscopes is this objective compatible with?
This objective is designed for standard microscope mounts and integrates with the iScope series and comparable Euromex optical systems; confirmation against the instrument's nosepiece and parfocal settings is advised.
