Olympus BX51 Fluorescence Microscope

The Olympus BX51 Fluorescence Microscope is a complete professional imaging system designed for advanced biological research, clinical diagnostics, and multi-color fluorescence applications. This turnkey system combines Olympus's renowned BX51 upright microscope platform with high-performance fluorescence illumination, a comprehensive objective set, and advanced imaging capabilities—ready for immediate deployment in research laboratories, clinical facilities, and educational institutions.

The Olympus BX51 represents the gold standard in upright research microscopy, featuring the UIS2 (Universal Infinity

System) optical design that delivers exceptional image quality, flat-field performance, and chromatic correction across the visible spectrum. The infinity-corrected optical path enables integration of fluorescence illuminators, DIC optics, polarization accessories, and camera systems without introducing optical aberrations.

The EXFO X-Cite 120 fluorescence illumination system provides high-intensity 120-watt metal halide illumination optimized for multi-color fluorescence imaging. The X-Cite 120 delivers broad-spectrum output from UV through visible wavelengths, enabling excitation of all common fluorophores including DAPI, FITC, GFP, TRITC, Texas Red, Cy5, and others. The metal halide lamp provides consistent, stable illumination with excellent color rendering and minimal intensity fluctuation—critical for quantitative fluorescence measurements and time-lapse imaging.

The BX-URA2 fluorescence illuminator features a 6-position filter cube turret with rotatable front, enabling rapid switching between fluorescence channels without disturbing the specimen. The rotatable front design allows the illuminator to be positioned for optimal ergonomics and workflow. The 6-position turret accommodates multiple filter sets for multi-color imaging applications.

The 3-position trinocular head provides exceptional flexibility for visual observation and digital imaging:

100% Eyepieces — All light directed to eyepieces for visual observation
100% Camera — All light directed to camera port for maximum imaging sensitivity
Split Beam — Light divided between eyepieces and camera for simultaneous viewing and imaging

This versatility enables operators to optimize the system for visual screening, digital documentation, or interactive imaging workflows.
The complete 5-objective set provides comprehensive magnification coverage:

Plan 4× — Low-magnification survey and specimen location
UPlanFL 10× — General-purpose observation and fluorescence imaging
UPlanFL 20× — Medium-magnification cellular imaging
UPlanFL 40× — High-resolution cellular and subcellular imaging
UPlanFL 100× Oil Immersion — Maximum resolution for fine cellular details and chromosome analysis

The UPlanFL (Universal Plan Fluorite) objectives provide excellent chromatic correction and flat-field performance optimized for fluorescence imaging.

The 100-watt quartz halogen lamphouse provides bright, even transmitted light illumination for brightfield, phase contrast, and DIC imaging. The Abbe-type condenser delivers proper Köhler illumination for optimal image quality and resolution.

The 6-position nosepiece with analyzer slot accommodates the complete objective set plus one additional position, with an integrated analyzer slot for polarization microscopy applications. The right-handed mechanical X-Y stage with slider holder provides precise specimen positioning and smooth, ergonomic operation.
