Plan semi-apochromatic PLM 50x/0.55 LWD IOS objective – 10.8 mm working distance, no cover glass correction (Euromex)

The Plan semi-apochromatic PLM 50x/0.55 LWD IOS objective is a microscope objective designed for high‑resolution imaging where flat field performance and sample clearance are priorities, ideally suited to laboratory and industrial inspection applications

• Plan semi-apochromatic correction
• 50x magnification, NA 0.55
• Long working distance 10.8 mm
• No cover glass correction

Precision imaging with reduced aberrations for measurable results

The plan semi-apochromatic design is engineered to reduce chromatic and spherical aberrations across the field, so that structures remain sharp from centre to edge. At 50x magnification with a 0.55 numerical aperture, the lens delivers a balance of resolution and depth of field that is advantageous for metrology and detailed inspection. Flat‑field correction means fewer focus adjustments are required when scanning across a specimen, which supports consistent, reproducible measurements and minimises operator time spent on corrections. Where documentation or image analysis is needed, the improved edge‑to‑edge clarity assists automated systems and manual measurement alike.

Extended working distance to protect samples and enable varied workflows

A 10.8 mm working distance provides generous clearance between the objective front and the specimen, allowing for thicker samples, fixtures or polarising accessories to be used without risk of contact. The absence of cover glass correction — explicitly stated as without cover glass correction — indicates that the lens is optimised for direct observation of specimens or for setups where no standard cover slip is applied. This configuration is particularly useful in industrial inspection, materials science and preparative workflows where sample thickness varies or where handling must be non‑contact. The long working distance also facilitates easier manipulation of samples under the lens, reducing the chance of accidental damage.

Robust optical choice for polarisation and long‑working‑distance applications

Built for polarisation microscopy contexts implied by the PLM designation, this objective combines LWD characteristics with the IOS optical approach to support stable, repeatable imaging in both routine inspection and specialised analytical tasks. The optical specification is suitable for integration into existing microscope stands and imaging chains that accept standard objectives; the precise match of magnification and numerical aperture aids compatibility with common camera sensors and illumination systems. For laboratories and workshops seeking a reliable, measurement-capable lens, the combination of plan correction, moderate NA and extended clearance fosters both image quality and practical usability.
