Universal 20.2 mm microscope objective lens designed for easy replacement and upgrade in education, research, and professional inspection settings. Key benefits Broad compatibility: Standard 20.2 mm interface fits most microscope models, allowing quick swaps and simple upgrades without special adapters. Improved image quality: Advanced optical pathway corrects spherical and chromatic aberrations to deliver parallel light paths and sharp images with minimal edge blur. Higher resolution than a magnifying glass: The 4X objective provides clearer, more detailed imaging for close inspection tasks. Versatile magnification design: Low magnification yields a wide, bright field for overall observation; higher magnification reveals fine details such as cells and dust. Main features Interface size: 20.2 mm standard mount for wide microscope compatibility. Objective power: 4X resolution objective suitable for detailed inspection work. Optical correction: Engineered to reduce spherical and chromatic aberrations for uniform clarity across the field. Ease of use: Simple replacement and upgrade process supports classroom, laboratory, and field workflows. Typical applications Banknote inspection and document examination for security and authenticity checks. Electronics and assembly work, including circuit board inspection and component placement. Educational and research microscopy for overview scans and detailed study of small structures such as cells and particulate matter. Technical highlights Standard 20.2 mm interface for compatibility with most microscope brands. Optical system tuned to produce parallel light paths and minimize edge blurring. 4X objective optimized for higher resolution than handheld magnifiers while maintaining a wide, bright view at lower magnifications. This objective lens offers a practical upgrade path for microscopy setups that need clearer imaging, reliable compatibility, and flexible magnification for both broad observation and finedetail work.
