iScope IS.7220 microscope objective — 20x magnification, NA 0.40

The iScope IS.7220 is a 20x microscope objective designed for detailed observation of prepared slides where a moderate numerical aperture and a short working distance are required.

• 20x magnification for detailed observations
• Numerical aperture 0.40 for improved resolution
• Working distance 5.1 mm for close-focus samples
• IOS PLi optical correction for flat-field imaging

Precision imaging where magnification meets usability

The 20x optical power combined with a numerical aperture 0.40 delivers a balanced trade-off between detail and depth of field, making this objective well suited to routine laboratory, educational and life‑science tasks. The moderate aperture improves resolution and contrast compared with lower-NA optics, while keeping illumination requirements manageable. The optical design described as IOS PLi indicates enhanced field flatness and correction across the field of view, which reduces peripheral blurring and simplifies image interpretation for frequent inspections.

Compact working distance that supports fine sample handling

A working distance of 5.1 mm enables focus on thin sections and coverslip-mounted preparations without excessive clearance, which benefits bench workflows that require precise stage movement or close access for micro-manipulation. The shorter working distance calls for careful specimen handling; however, it also facilitates higher numerical aperture performance in a small optical package. For routine brightfield observation and documentation of cellular detail, this combination supports efficient throughput and consistent image quality.

Reliable build and clear identification for workshop procurement

Manufactured by Euromex, the objective is identified by the article number IS.7220, which helps procurement and inventory control in laboratory and educational supply chains. The designation within the iScope series signals a family of compatible optics for straightforward swapping between magnifications when a microscope accepts standard objectives. Clear labelling and consistent optical specifications assist quality assurance processes and reduce the risk of mismatched components during instrument maintenance.

FAQ

What magnification and resolution does this objective provide?
The iScope IS.7220 offers 20x magnification with a numerical aperture of 0.40, which improves resolution and contrast for routine laboratory imaging while maintaining sufficient depth of field for general slide work.

Which specimens are best viewed with this objective?
Thin, coverslip-mounted preparations and standard histological sections are well suited to an objective with a 5.1 mm working distance and moderate aperture; the optical balance supports cellular and tissue-level observations.

Is the optical correction suitable for imaging across the full field of view?
Yes—the IOS PLi designation indicates measures to flatten the field and reduce edge aberrations, resulting in sharper detail across much of the visible area when used with appropriate tube optics.

Can this objective be integrated into existing teaching microscopes?
The item is part of the iScope series and is labelled clearly as IS.7220 for procurement; compatibility depends on the microscope’s objective mounting standard, so checking the instrument’s nosepiece and parfocal spacing is recommended.

How does the working distance affect handling and illumination?
A 5.1 mm working distance allows close focus on specimens but requires careful stage movement and positioning; illumination should be adjusted to match the 0.40 aperture for optimal contrast.
