Universal 20.2 mm microscope objective designed for easy integration and reliable, imaging in educational and research environments. Key benefits Broad compatibility: Standard 20.2 mm interface fits most biological microscope models, simplifying upgrades and replacements. Improved image fidelity: Infinite optical system with plan objective correction reduces spherical aberration and distortion, producing parallel light paths and clear images without edge blurring. resolution 20X magnification: Suitable for cytology, microbiology, and environmental observation, useful for both initial surveys and further detailed study. Flexible observation range: Lower magnification provides a wide field of view and brightness for overall scanning; higher magnification enlarges fine details for analysis of small structures such as cells and particulates. Professional observation performance: Optical design focused on accurate, flatfield imaging to support research and teaching tasks. Specifications Interface diameter: 20.2 mm Optical design: Infinity corrected, plan objective Nominal magnification: 20X Primary applications: Educational labs, research microscopy, environmental monitoring Practical use scenarios Classroom and teaching laboratories: Fast installation on existing microscopes for lectures and practical exercises where wide field views and consistent image quality are required. Research in cytology and microbiology: Clear, flatfield 20X imaging for sample screening, documentation, and preparation for higher magnification analysis. Environmental sample examination: Observation of water samples, particulates, and microfauna in field or lab settings where detail and low distortion are important. Why this objective solves common problems Eliminates edge blur and distortion that interfere with accurate observation and imaging. Provides a standardized, easy to mount interface to reduce downtime during upgrades or replacements. Balances field of view and detail so users can efficiently locate areas of interest and then resolve fine structures without changing optical systems. This objective is a practical choice for laboratories and classrooms that require consistent optical performance, easy compatibility, and reliable 20X resolution for a variety of microscopy tasks.
