Olympus LPlan N 40x Objective with Correction Collar

The Olympus LPlan N 40x objective is specifically engineered to provide exceptional working distance while maintaining high optical performance and versatility through an integrated correction collar. The "LPlan" designation indicates Long Plan optics, combining extended working distance with flat-field correction for applications requiring both high magnification and exceptional clearance. At 40x magnification with 0.60 numerical aperture, this objective delivers excellent resolution and light-gathering capability for detailed cellular imaging while maintaining a working distance of 3.40-4.10mm—significantly greater than standard 40x objectives. This extended working distance is essential for imaging through thick specimens, culture vessels, microfluidic devices, or when experimental access is required for micromanipulation equipment. The integrated correction collar enables precise compensation for variations in coverslip thickness from 0 to 1.00mm, mounting media refractive index, and specimen preparation variations, ensuring optimal optical performance across diverse applications. This wide correction range makes the objective particularly valuable for imaging specimens without coverslips, thick coverslips, or non-standard preparations. The flat-field correction ensures sharp, distortion-free images across the entire field of view. The RMS thread mount ensures compatibility with a wide range of microscope platforms. Factory-new condition ensures optimal performance and reliability for demanding research and industrial applications requiring both high resolution and exceptional working distance.
