Universal 20.2mm Interface and Resolution 20X Objective This Plan Infinity optical objective with a standard 20.2mm interface is designed for easy integration with most biological microscopes. It delivers reliable, resolution imaging for educational and research environments and is well suited for upgrades or replacements on existing microscope systems. Key benefits Broad compatibility: Standard 20.2mm interface fits most biological microscope models, simplifying installation and replacement. optical correction: Plan Infinity optical design effectively corrects spherical aberration and distortion, producing parallel light paths and sharp images across the field without edge blurring. resolution 20X performance: The 20X objective provides detailed imaging suitable for cytology, microbiology, and environmental observation. Use it for initial imaging or as part of a higher magnification workflow. Practical magnification workflow: Supports widefield, brightness observation at lower magnifications and detailed enlargement at higher magnifications when combined with appropriate eyepieces and nosepiece settings. Features and performance Interface size: 20.2mm standard connection for wide microscope compatibility. Optical design: Plan Infinity objective for minimized spherical aberration and distortion, maintaining clarity from center to edge. Use cases: Designed for classroom labs, research benches, and diagnostic training where dependable image quality and easy interoperability matter. Example applications Cytology labs: Examine cell morphology and prepare samples for further magnification study. Microbiology work: Observe microorganisms and initial colony structure before switching to higher magnification objectives. Environmental monitoring: Inspect water or soil samples for particulates, microorganisms, and small structures. Who this is for Educators and students in laboratory courses Researchers needing a reliable 20X objective for routine imaging and as part of multiobjective setups Lab technicians upgrading or replacing objectives on compatible biological microscopes This objective provides a balance of compatibility and optical performance for users who need consistent, clear images across a variety of educational and research tasks.
