microscope objective iScope IS.7120 — 20x, NA 0.40 (Euromex)

A microscope objective iScope IS.7120 designed to deliver reliable mid-range magnification performance for educational and life‑science applications, optimised for routine imaging and close-up sample work.

• 20x magnification, mid-range optical power
• Numerical aperture 0.40 for fine resolution
• 3.5 mm working distance for close specimens

Mid-range magnification that improves routine image clarity

The 20x specification positions this optical element between low- and high-power objectives, making it a versatile choice for both classroom demonstrations and laboratory tasks. With a numerical aperture of 0.40, the lens collects a substantial amount of light, which directly enhances resolution and contrast; this means finer structural details become distinguishable without requiring higher magnifications. In practical terms, the combination of magnification and NA produces crisp, informative images suitable for documentation and comparative observation, while keeping illumination demands moderate.

Short working distance for detailed specimen inspection

A working distance of 3.5 mm indicates that the objective is intended for observations where the specimen or cover glass is close to the lens. This compact focal geometry supports high-detail inspections such as cell morphology checks or thin-section examinations, where proximity improves optical coupling and image sharpness. Operators should be mindful of the reduced clearance when manipulating samples or slide mounts; however, the closer spacing is an advantage when maximising numerical aperture and resolving power for demanding visual tasks.

Built for education and routine life‑science workflows

Engineered for robust everyday use, this optical component fits naturally into teaching microscopes and standard laboratory stands. The balanced optical parameters make it straightforward to integrate into multi-objective turrets and standard optical tubes, providing consistent performance across sessions. For educational environments, the pairing of 20x power with a 0.40 NA offers an instructive middle ground that reveals cellular detail while remaining forgiving during handling. In research or bench‑side contexts, the same characteristics enable repeatable observations that support documentation and collaborative review.

FAQ

What magnification does this objective provide?
The microscope objective iScope IS.7120 provides 20x magnification suitable for mid-range imaging tasks and routine laboratory observations.

What numerical aperture and optical performance can be expected?
This objective is specified with a numerical aperture of 0.40, which supports improved resolution and light gathering compared with lower‑NA lenses at the same magnification.

How close can the sample be to the lens?
The working distance is 3.5 mm, so specimens and cover glasses will be positioned close to the front element, improving resolving power but requiring careful slide handling.

Which applications are appropriate for this objective?
The design is well suited to education and life science contexts, providing a balance of magnification and resolution for classroom demonstrations, routine microscopy and bench‑level inspections.

Is this objective compatible with standard microscope setups?
The iScope IS.7120 is intended as a standard objective for use with compatible microscopes and turrets; confirm mechanical fitting and optical tube length with the instrument documentation before installation.
