Precise imaging where detail matters

The combination of 40x magnification and a numerical aperture of 0.65 provides a measurable increase in resolving power and image contrast compared with lower-NA lenses. This optical performance is particularly beneficial for material inspections, routine laboratory checks and teaching demonstrations where distinguishing fine structure is essential. The design emphasises consistent image quality and repeatable results, supporting efficient workflows and reducing the need for post-processing of images.

What the optical specifications mean in practice

A numerical aperture (0.65) determines the objective’s ability to gather light and resolve fine detail; higher NA yields better resolution and shallower depth of field. The 0.7 mm working distance indicates the clearance between the front lens and the specimen at focus, allowing observation of very small or low-profile samples. For practical purposes, these parameters mean the lens is optimised for high-detail surface observation rather than deep, thick specimens. Technically minded teams will value the clear trade-off between resolution and working distance when specifying objectives for inspection rigs or teaching microscopes.

Integration, suitability and practical benefits

Designed as a straightforward optical component, the lens offers Euromex build quality and is suitable for educational laboratories, quality-control benches and other microscope-based inspection stations. The compact optical geometry simplifies storage and handling while delivering consistent performance across comparable setups.

FAQ

What magnification does this objective provide?
The lens delivers 40x magnification, suitable for high-detail observation in laboratory and teaching contexts.

How does the numerical aperture affect image quality?
The 0.65 numerical aperture increases light-gathering and resolution, producing sharper, higher-contrast images than lower-NA alternatives.

What does a 0.7 mm working distance imply for sample handling?
A 0.7 mm working distance means the objective focuses very close to the specimen surface, ideal for thin or low-profile samples but requiring careful handling to avoid contact.
