iScope IS.7420 microscope objective — 20x, NA 0.50 (Euromex)

The iScope IS.7420 microscope objective is a 20x laboratory objective designed for detailed life‑science and inspection imaging with a compact working distance for high‑contrast close observation

• 20x magnification, high-resolution imaging
• Numerical aperture 0.50 for enhanced contrast
• Working distance 1.4 mm for close-up observation
• iScope series precision optics by Euromex

Precision optics for reliable high‑contrast imaging

The 20x objective delivers controlled magnification while the 0.50 numerical aperture improves resolution and light‑gathering capability, which is essential when distinguishing fine structures under transmitted or reflected illumination. The optical design, specified as a PLFi objective, is intended to provide a flat field and consistent imaging across the view; this reduces the need for frequent refocusing during routine inspections. These characteristics translate into measurable gains in image clarity and throughput for microscopy workflows where detail matters.

Compact working distance that supports detailed procedures

A 1.4 mm working distance positions the front lens close to the specimen, supporting high‑NA performance and finely resolved contrast at medium magnification. While shorter working distances require careful handling, the benefit is improved numerical aperture utilisation and better signal collection from small or low‑contrast samples. For laboratory environments engaged in cell culture observation, component inspection or material analysis, the combination of 20x power and close working distance enables concise, reproducible imaging results without complex optical add‑ons.

Integration and practical advantages for lab setups

Delivered as part of the iScope series, this objective is designed for compatibility with standard microscope turret mounts used in life‑science settings. The compact mechanical form factor and consistent optical parameters make it suitable for routine documentation and quality checks where stable performance is required. The optical specifications are intended to reduce measurement variability, supporting a more efficient analytical routine and a dependable basis for comparative image evaluation across multiple samples.
