Zeiss LD Plan Neofluar 20x Objective

The Zeiss LD Plan Neofluar 20x objective is specifically engineered to provide exceptional working distance while maintaining high optical performance, making it essential for applications requiring experimental access or imaging through thick specimens. The "LD" (Long Distance) designation indicates a working distance significantly greater than standard objectives at this magnification, enabling imaging through thick tissue sections, culture vessels, or other preparations where standard objectives would be impractical. At 20x magnification with 0.40 numerical aperture, this objective delivers excellent resolution and light-gathering capability for detailed cellular imaging while maintaining the extended working distance. The Plan Neofluar optical design combines flat-field correction with fluorescence optimization, making this objective suitable for both brightfield and fluorescence applications. The 7.4mm working distance is exceptional for a 20x objective, providing ample clearance for imaging through thick specimens, culture dishes, or microfluidic devices while allowing room for micromanipulators and experimental apparatus. The M27 thread mount ensures compatibility with Zeiss Axio and other infinity-corrected platforms. LD objectives are indispensable tools in applications requiring both high resolution and experimental access including thick-tissue imaging, organoid culture studies, and any application where standard working distances are insufficient.
