🔧 Product Description

The Olympus Plan N 4× objective (PLN4X) is a high-quality low-power lens designed for overview and wide-field imaging in laboratory, clinical, and educational settings. With 4× magnification and a numerical aperture of 0.10, this objective delivers a broad field of view paired with consistent clarity—ideal for surveying slides, mapping sample regions, and imaging larger specimens prior to switching to higher magnifications. The Plan optical design corrects common optical distortions such as chromatic and spherical aberrations, providing flat, crisp imaging across the entire field. This makes it especially useful for brightfield microscopy, initial specimen scanning, and documentation tasks where uniform image quality is essential. The working distance of approximately 16.5 mm gives researchers ample space between the specimen and objective lens, which is particularly beneficial when using auxiliary tools or sample holders during preliminary imaging. The standard RMS threaded mount ensures broad compatibility with most upright microscopes used in research, teaching, and clinical laboratories.

🔎 Typical Applications

• Low-power brightfield microscopy
• Slide and specimen overview imaging
