Olympus SWTLU-C Wide Field Tube Lens, 180mm Focal Length

The Olympus SWTLU-C Super Widefield Tube Lens is an advanced optical component designed to provide exceptional field coverage and superior image quality in infinity-corrected microscope systems. With a field number of 26.5 and advanced aberration correction, this tube lens enables observation and imaging of larger sample areas with outstanding optical performance across the entire field.

The super widefield capability with field number 26.5 provides significantly expanded field coverage compared to standard tube lenses. This large field of view enables observation of greater sample areas in a single field, improving workflow efficiency by reducing the need for stage repositioning and providing better contextual understanding of sample features. The expanded field is particularly valuable for applications such as pathology slide scanning, large tissue section analysis, materials inspection, and any workflow where observing the maximum possible area is advantageous.

Advanced aberration correction is a key feature of the SWTLU-C design. The precision optical engineering reduces both spherical and chromatic aberration, ensuring superior image quality across the entire expanded field. This correction maintains sharp focus, accurate color rendition, and high contrast from center to edge, which is essential for quantitative image analysis, high-quality documentation, and applications requiring the highest optical fidelity.

Optimized for use with Olympus UIS2 (Universal Infinity System 2) objectives, the SWTLU-C tube lens maintains the optical performance and specifications of UIS2 objectives while providing the expanded field of view and enhanced aberration correction. This allows you to leverage your existing UIS2 objective collection while gaining the benefits of super widefield observation and superior image quality.

The compact form factor is specifically designed for flexible instrumentation integration and OEM applications. The small size enables incorporation into custom microscopy systems, automated imaging platforms, and space-constrained setups where standard tube lenses may be too large. This makes the SWTLU-C ideal for system integrators, instrument manufacturers, and researchers building custom microscopy solutions.

Precision Japanese manufacturing ensures reliable optical performance and consistent image quality. The robust construction provides long-term stability in demanding research and production environments where large-area observation, superior image quality, and flexible integration are essential.
