iScope IS.7720 microscope objective — 20× / NA 0.40 by Euromex

The iScope IS.7720 is a 20× microscope objective designed for high-resolution observation in education and life-science applications, offering a compact working distance for close-sample imaging.

• 20× magnification for detailed observation
• Numerical aperture 0.40 for improved resolution
• Working distance 5 mm for close-up samples
• PLPH design for sharp image correction

Outstanding detail where it matters

This optical component delivers 20× magnification with a numerical aperture of 0.40, giving a clear balance between resolving power and depth of field. The elevated aperture improves light-gathering capacity, which results in finer detail when imaging stained preparations or small features on material samples. The design supports consistent contrast and sharpness across the field, making it suitable for teaching laboratories and routine life‑science work where reproducible visual results are required.

Compact working distance for close inspections

A working distance of 5 mm enables examination of specimens that need to be positioned very close to the lens, such as mounted slides with coverslips or specimens in small containers. While this close proximity demands careful sample handling, it allows higher numerical apertures to be realised in a compact form factor. For users unfamiliar with optical trade-offs: higher aperture increases resolution but reduces the available clearance between lens and sample, so careful focus control and sample mounting improve outcome reliability.

Practical optical design explained

The objective’s PLPH designation indicates a planachromatic, phase-corrected hybrid design that reduces field curvature and chromatic aberration, yielding a flatter field and more accurate colour rendition across the image. This correction means fewer adjustments are needed for evenly illuminated images and simplifies documentation tasks. The optical correction benefits both novices and experienced microscopists by lowering the time spent compensating for aberrations during routine observation.

Integration and application guidance

The lens is supplied as part of a standard objective range and is compatible with common microscope nosepiece systems; it suits educational, clinical and industrial inspection workflows that prioritise clear, corrected images at medium magnification. When used with appropriate illumination and condenser settings, the objective supports reproducible results for documentation and measurement tasks. For applications requiring alternative working distances or higher magnification, consult the available range within the same series to match task-specific needs.

FAQ

What magnification and aperture does this objective provide?
The Euromex iScope IS.7720 objective offers 20× magnification with a numerical aperture of 0.40, providing a balance of resolution and depth of field suitable for detailed imaging.

Is the working distance sufficient for mounted specimens with coverslips?
Yes, the 5 mm working distance is intended for close-sample observation and is compatible with standard mounted slides and coverslips, though careful focusing is recommended due to the short clearance.

What does PLPH mean and why is it important?
PLPH refers to a planachromatic, phase-corrected hybrid design that reduces field curvature and chromatic aberration, resulting in a flatter field and improved colour accuracy for clearer images with less adjustment.

Can this objective be used for both teaching and light‑microscopy inspection tasks?
The objective is suitable for education and routine life‑science or inspection work where medium magnification and corrected optics are required, offering reproducible imaging across common laboratory tasks.

Are there references documenting the specification values?
Specification details for the lens, including magnification, working distance and numerical aperture, are listed in the supplied education and life-science PDFs referenced in the product documentation.
