Product overview This 20X objective lens is designed for use with standard 20.2mm microscope interfaces, offering a straightforward upgrade or replacement for most biological microscopes used in education and research. Its infinite optical system and plan correction deliver clear, lowdistortion images across the field of view, making it suitable for both general observation and detailed study. Key benefits Wide compatibility: Standard 20.2mm interface fits the majority of biological microscope models, simplifying installation and part replacement. Improved image quality: Plan objective design corrects spherical aberration and distortion, producing parallel light paths and sharp images with minimal edge blur. Versatile magnification: 20X magnification provides a balance between a broad field of view and the resolution needed to examine fine structures. Practical for teaching and research: Bright, widefield lowmagnification performance for overview observation and sufficient enlargement to study small structures like cells and particulates. Easy integration: Designed as a dropin upgrade for infinity optical systems, enabling enhanced performance without changing the microscope tube or system architecture. Performance and attributes Optical system: Infinitecorrected optics with plan objective correction for reduced aberration and uniform image flatness across the field. Interface size: Standard 20.2mm diameter for broad crosscompatibility with biological microscope eyepiece tubes and nosepieces. Primary use: 20X objective suitable as an initial imaging objective or as part of a multiobjective set for further magnified observation. Imaging quality: Emphasis on clear centertoedge resolution and reliable reproduction of small features. Why customers need this product worn or damaged objectives with a compatible, quality 20X option that restores image clarity. Upgrade older microscopes to benefit from plancorrected, infinite optical performance without complex modifications. Maintain consistent image quality across multiple microscopes in classrooms or labs by using a standardized 20.2mm interface objective. Typical applications and scenarios Classroom microscopy: Use as a primary teaching objective to demonstrate cell structure and basic microbiology with a bright, wide field of view. Laboratory research: Employ as an initial or intermediate objective for cytology and microbiology workflows before switching to higher magnifications for detail work. Environmental monitoring: Inspect particulate matter, plankton, or microfauna in environmental samples where clear contrast and edgetoedge sharpness are needed. What it solves Reduces edge blurring and distortion common with nonplan objectives, improving measurement reliability and visual clarity. Simplifies equipment maintenance and upgrades by matching the widely used 20.2mm standard interface. Delivers a practical balance between overview observation and detail resolution, supporting diverse educational and research tasks. Compatibility note Designed for microscopes with a 20.2mm objective interface and infinity optical systems. Suitable for many biological microscope models that accept standard 20.2mm objectives.
