EcoBlue EC.7020 microscope objective — 20x, NA 0.40 (Euromex)

EcoBlue EC.7020 microscope objective delivers 20x magnification with a short working distance, suited to routine laboratory and educational microscopy applications

• 20x magnification for clear intermediate detail
• Numerical aperture 0.40 for good resolution
• 2.0 mm working distance for proximate focusing
• Suited to educational and routine laboratory microscopy

Consistent optical performance for reliable imaging

The EcoBlue EC.7020 microscope objective combines 20x magnification with a 0.40 numerical aperture, a pairing that balances enlargement with light-gathering capability to deliver clear intermediate-level detail. The numerical aperture expresses the objective’s ability to resolve fine structures and influence image brightness; a 0.40 numerical aperture provides noticeably improved resolution over lower-NA objectives while maintaining adequate depth of field. This makes the lens appropriate where clarity of sub-millimetre features is important without requiring specialist high-NA condensers.

Compact working distance for practical sample handling

A 2.0 mm working distance allows close access to specimens, which is advantageous when observing small mounted samples or when using thin coverslips in standard laboratory preparations. The relatively short working distance reduces the optical path between sample and lens, improving image crispness for near-surface features. For users who require consistent focus at intermediate magnifications, this configuration simplifies focusing routines and supports repeatable imaging workflows in teaching and routine inspection tasks.

Designed to support education and routine laboratory workflows

Engineered for routine laboratory and educational environments, this objective offers a pragmatic mix of performance and ease of use. The combination of 20x magnification and 0.40 numerical aperture supports a broad range of common applications — from student practicals to basic materials inspection — without the need for specialist optics. Equipment purchasers seeking dependable, accessible optical components will find this lens a practical addition to standard microscope sets; for further specification clarifications, the Metav Werkzeuge technical advisors can provide measured data and application guidance.
