Optical Performance

• UPLSAPO Super Apochromat objectives: These high-end objectives offer exceptional resolution and contrast, with chromatic aberration correction from the UV to the near-infrared region.
• PLAPON Plan Apochromat objectives: Designed for excellent resolution and contrast, these objectives are available in 1.25X and 2X magnifications.
• UPLFLN (UPLFLN-PH) Plan Fluorite objectives: These objectives provide flat images with high transmission up to the near-infrared region, making them ideal for brightfield and phase contrast observations.
• PLN (PLN-PH) Plan Achromat objectives: Suitable for a range of clinical and research applications, these objectives offer excellent flatness up to FN 22 in transmitted brightfield and phase contrast observations.

• Abbe condenser (NA 1.1): Suitable for magnifications from 4X to 100X.
• Swing-out condenser (NA 0.9): Suitable for magnifications from 1.25X to 100X.
• Achromat condenser (NA 0.9): Provides excellent performance for phase contrast observation.

Illumination

The Olympus BX43 features a high-performance LED illumination system with a color rendering index (CRI) of 92, providing bright, uniform illumination with natural color reproduction. The LED lamp has a long lifespan of approximately 60,000 hours, reducing maintenance and replacement costs.

The microscope's Light Intensity Manager automatically adjusts the brightness when changing objectives, eliminating the need for manual adjustments and reducing eye strain during prolonged use.

Observation Tubes and Ergonomics

• Tilting trinocular tube: This ergonomic tube allows users to adjust the viewing angle from 5° to 35°, reducing neck and back strain during extended use. The trinocular design enables the attachment of a digital camera for imaging and documentation.
• Widefield binocular and trinocular tubes: These tubes provide a wide field of view (FN 22) for comfortable observation. The trinocular models allow the attachment of a digital camera.
• Super widefield trinocular tube: With an even larger field of view (FN 26.5), this tube is ideal for applications requiring a broad overview of the sample.

The BX43's ergonomic design extends to the stage and focus controls. The rackless stage with a ceramic-coated surface provides smooth, precise movement with minimal maintenance. The stage handle extender allows users to operate the stage while resting their arms on the desk, reducing fatigue during prolonged use.

Modular Design and Versatility

• Brightfield
• Darkfield
• Phase contrast
• Polarized light
• Fluorescence (reflected and transmitted)

• Magnification changers
• Intermediate tubes for additional accessories
• Digital cameras for imaging and documentation
• Motorized components for automated operation

This versatility makes the BX43 an excellent choice for multi-user environments, such as clinical laboratories, research institutions, and educational facilities.
