Plan Apo PL-AMIi 100x/0.90 — Objective lens, 100×, 0.90 NA, 1 mm working distance (M26)

The Plan Apo PL-AMIi 100x/0.90 is a brightfield/darkfield IOS objective engineered for industrial and laboratory microscopes, offering a compact parfocal spacing and a long working distance for specimens that do not use a cover glass.

• Plan apochromatic optics for precise colour correction
• 100× magnification with 0.90 numerical aperture
• Long 1 mm working distance for thicker specimens
• M26 thread, 45 mm parfocal for easy swapping

Exceptional optical performance for demanding inspections

The objective combines a plan apochromatic design with a high numerical aperture (0.90 NA) and 100× power to produce images with improved flatness and corrected chromatic aberration. This optical correction reduces the need for repeated refocusing and colour adjustments, which increases throughput during inspection routines. The result is sharper contrast and better detail resolution for fine structures, making the lens suitable where precise measurement and confident visual assessment are required.

Practical benefits for workflow and sample handling

A defining advantage is the 1 mm working distance, which permits observation of samples that are thicker than typical cover-glass-mounted slides or that require manipulation under the objective. The absence of cover-glass correction means the objective is optimised for direct sample observation rather than for standard cover-slip thicknesses; this simplifies preparation for certain materials and speeds up batch inspections. The 45 mm parfocal spacing supports rapid objective swapping without significant refocusing, improving operational efficiency across multi-magnification routines.

Mounting compatibility and mechanical design considerations

The lens features an M26 thread, compatible with microscopes and turret systems designed for IOS-style objectives. The mechanical parfocality (45 mm) and the standard mounting make integration straightforward in existing optical benches and inspection stations. Because the objective is specified without cover-glass correction, it is particularly well suited to applications where samples are examined in situ or on substrates that would otherwise interfere with corrected objectives.

Choosing this lens for application-specific imaging

Selecting this objective is a rational choice when the priority is a combination of high magnification, strong light-gathering capability and close sample access. The brightfield/darkfield capability extends versatility: brightfield for transmitted-light contrast and darkfield to enhance edge detail and small particle visibility.

FAQ

Is this objective suitable for samples without a cover glass?
Yes. The Plan Apo PL-AMIi 100x/0.90 objective (SKU AI.8100) is specified without cover-glass correction and is therefore appropriate for direct observation of specimens that are not mounted beneath a cover slip.

Can the objective be used for both brightfield and darkfield techniques?
Yes. The optical design supports brightfield and darkfield illumination modes, allowing the same objective to highlight transmitted contrast or enhance edge and particle visibility depending on the illumination setup.

What does a 45 mm parfocal distance mean for the workflow?
A 45 mm parfocal distance indicates standard mechanical spacing that enables objective changes with minimal refocusing, improving inspection speed when alternating magnifications on compatible microscope stands.

Will the M26 thread fit standard turret systems?
The M26 thread follows IOS objective mounting conventions; compatibility depends on the microscope turret or adapter. Metav Werkzeuge can advise on suitable adaptors or mounting options for integration.
