20X Plan Objective Lens with Universal 20.2mm Interface Overview A resolution 20X plan objective designed for laboratory and educational microscopes with a standard 20.2mm interface. The objective uses an infinite optical system and plan correction to deliver clear, distortion images across the field of view while remaining compatible with most biological microscope brands for easy upgrade or replacement. Key benefits Broad compatibility: Standard 20.2mm interface fits most biological microscope tubes, simplifying installation and replacement in teaching and research settings. Clear, flat images: Plan objective design corrects spherical aberration and distortion so light paths remain parallel and edges stay sharp, reducing the need for repeated focusing and adjustment. Reliable resolution performance: 20X magnification provides the resolution needed for initial imaging and for preparing samples for further observation. Versatile observation range: Low magnification yields a wide, bright field for overall sample orientation; higher magnification reveals fine details of small structures such as cells and particulates. Time and workflow savings: Stable, distortion images help users capture usable views faster and focus on analysis rather than corrective adjustments. Features and specifications Interface diameter: 20.2mm standard mounting for broad compatibility. Optical design: Infinite optical system with plan objective correction for minimized spherical aberration and edge distortion. Magnification: 20X objective suitable for general resolution observation tasks. Application scope: Designed for educational laboratories, research work, and environmental sample analysis. Practical use scenarios Educational laboratories: Quick upgrades to classroom microscopes for demonstrations and student labs where consistent, flatfield imaging improves learning and reduces setup time. Cytology and microbiology teaching: Use as a primary objective for inspecting cell morphology and microbial preparations, or as an intermediate step before switching to higher magnifications. Environmental monitoring and field sample analysis: Examine water, soil, and particulate samples to identify small structures and contaminants with clear, edgetoedge imaging. Compatibility and installation Designed to integrate with most biological microscopes that accept a 20.2mm objective mount. Installation is straightforward, enabling fast replacement or upgrade without extensive modification. This objective is intended for professional observation and educational use where consistent optical performance and crossbrand compatibility are required.
