Olympus WHN 10X Widefield Microscope Eyepiece | FN22

The Olympus WHN 10x eyepiece is specifically engineered to provide high-quality, comfortable observation for Olympus BX and IX series microscopes with reticle capability for measurement applications. The "WHN" designation indicates Olympus's wide-field high-eyepoint negative eyepiece series, designed for comfortable extended viewing with or without eyeglasses. At 10x magnification with field number 22, this eyepiece delivers a wide field of view essential for specimen overview, navigation, and detailed examination. The wide-field optical design maximizes the observable area, providing a larger field of view compared to standard eyepieces and reducing the need for frequent specimen repositioning. The high eyepoint design positions the exit pupil farther from the eyepiece lens, enabling comfortable viewing for eyeglass wearers without removing their glasses while maintaining full field of view. The integrated reticle retaining ring accepts standard 24mm diameter measuring reticles, enabling precise measurements, counting, and dimensional analysis directly through the eyepiece. The 30mm eyetube diameter ensures compatibility with Olympus BX and IX series microscopes equipped with standard 30mm eyetube observation heads. Factory-new condition ensures optimal optical performance and reliable operation for demanding laboratory, research, and clinical applications requiring both comfortable viewing and measurement capabilities.
