Euromex Infinity-corrected 45 mm Plan Apo PL‑AMi 100×/0.90 BD objective — precision optics for high-magnification inspection

Euromex Infinity-corrected 45 mm Plan Apo PL‑AMi 100×/0.90 BD objective is an infinity‑corrected, plan apochromat lens designed for demanding high‑magnification imaging where resolution and colour fidelity are essential

• Plan apochromat optics for high image fidelity
• 100× magnification with NA 0.90
• 1 mm working distance for close inspection
• M26 thread, infinity‑corrected 45 mm interface

High-resolution imaging through a large numerical aperture

The lens combines a 100× magnification with a numerical aperture (NA) of 0.90, which directly improves light‑gathering capability and lateral resolution. A higher NA reduces diffraction limits and yields finer detail in the image, making it suitable for micro‑structural analysis and precision inspection tasks. The Plan apochromat design corrects chromatic and field aberrations across the field of view, so the objective delivers a flat image with accurate colour rendition — critical when documenting surface features or performing image‑based measurements.

Secure mechanical interface and system compatibility for routine use

With an M26 mounting thread and an infinity‑corrected 45 mm interface, the lens fits standard turret adaptors and modern infinity microscopes that accept a 45 mm optical layout. The mechanical specification ensures repeatable positioning and straightforward integration into inspection rigs or microscope heads. The compact mount and standard interface simplify swaps between objectives and reduce downtime during set‑up, supporting reliable throughput in production or laboratory environments.

Short working distance tailored for high‑detail applications

A 1 mm working distance indicates extremely close proximity between the front lens and the specimen, which is advantageous for maximising resolution at high magnifications but requires careful sample preparation and handling. The objective is specified without cover glass correction, so it is optimised for specimens viewed without a cover slip; using a cover glass will introduce focus shifts and aberrations. This configuration suits metallographic inspections, surface topology checks and other tasks where specimens are presented uncovered or held within fixtures.

FAQ

What magnification and resolution does this objective provide?
The objective offers 100× magnification with a numerical aperture of 0.90, delivering high lateral resolution and improved light collection for detailed inspections.

Can this objective be used with cover slips?
No; the lens is specified without cover glass correction, so it is optimised for specimens viewed without a cover slip. Use with a cover glass will change focus and can introduce aberrations.

Which microscope standards and mounts are compatible?
Compatibility requires an infinity‑corrected system with a 45 mm optical interface and a turret or adaptor accepting an M26 thread for secure mounting.

What does a 1 mm working distance mean for handling and samples?
A 1 mm working distance provides close proximity for maximum resolution but necessitates careful sample positioning and protective handling to avoid contact with the front element.

Is this objective suitable for metallography and surface inspection?
Yes; the combination of Plan apochromat correction, high NA and 100× magnification makes the objective well suited to metallographic and surface topology tasks where uncovered specimens are examined.
