DX.7905-R microscope objective — Euromex, 5× / 0.15, M25, 20 mm WD

A DX.7905-R microscope objective designed for infinity-corrected, plan semi-apochromatic imaging at low magnification, optimised for clear, distortion-free overview observations

• Infinity-corrected for accurate imaging
• Plan semi-apochromat optical correction
• 5× magnification, NA 0.15, 20 mm working distance
• M25 thread and stress-free mounting

High‑precision optics for consistent overview imaging

The DX.7905-R delivers a combination of infinity-corrected design and plan semi-apochromat correction that reduces field curvature and colour fringing at low magnification. This optical arrangement translates into flatter images across the field, which is particularly useful during assembly inspections, material overviews or routine sample scanning. The 5× magnification and numerical aperture of 0.15 balance depth of field and resolution to show sufficient detail while preserving a broad field of view. The explanation of the optical terms supports purchasing decisions: “infinity-corrected” means the objective projects parallel rays to the tube lens for modular optical setups; “plan” indicates field flattening for a consistent image from centre to edge.

Practical mechanical design for straightforward integration

Mechanical features focus on ease of use in existing setups: the M25 thread ensures compatibility with many objective mounts and adapters, while the stress-free mounting reduces internal lens strain that can affect image quality and long-term stability. The 20 mm working distance provides comfortable access above the specimen, allowing room for light sources, manipulators or pick-and-place heads without sacrificing image performance. These characteristics make this objective suitable for retrofit in workbenches, inspection stations and laboratory microscopes where mechanical fit and sample access are important considerations.

Application guidance and handling recommendations

This objective is supplied without coverslip correction, so it is optimised for direct observation of specimens or samples where no coverslip is used; when samples are examined under a coverslip, chromatic or focus offsets may occur and should be compensated elsewhere in the optical path. The optical and mechanical specifications make the component well suited to industrial inspection, educational demonstrations and routine quality control tasks. For users unfamiliar with optical indices, the numerical aperture indicates light-gathering ability and affects contrast and resolution; with NA 0.15, expect a practical compromise between contrast and depth of field ideal for overview imaging.

FAQ

Is this objective compatible with standard infinity-corrected microscope systems?
The DX.7905-R is an infinity-corrected objective intended for use in infinity optical systems; confirm tube lens specifications on the host microscope before installation.

Can the objective be used with a coverslip in place?
This objective is supplied without coverslip correction, so using a coverslip may introduce focus or chromatic offsets that require optical compensation elsewhere.

Which thread is required for mounting the objective?
The objective uses an M25 thread for attachment; appropriate M25 adaptors or holders must be used for secure integration.

What types of inspection tasks suit this objective best?
The combination of 5× magnification, NA 0.15 and a 20 mm working distance makes it well suited for general overview inspections, material checks and educational demonstrations where a broad field and comfortable sample access are priorities.

Who manufactures this objective and where can further information be requested?
The objective is manufactured by Euromex Microscopen bv; for detailed specifications or clarifications consult the manufacturer data sheet or contact Metav Werkzeuge for advice and supply options.
