Olympus BX51 Key Features
Universal Infinity System (UIS) Optics
At the core of the BX51's exceptional performance is Olympus' proprietary Universal Infinity System (UIS) optical system. UIS optics provide enhanced contrast, resolution, and a wider field of view, resulting in excellent image quality.
Ergonomic Y-Shaped Design
The BX51 features a comfortable, ergonomic Y-shaped body that places all essential controls within easy reach of the user. This thoughtful design allows researchers to make adjustments without taking their eyes off the specimen, enabling more efficient and focused work.
Versatile Illumination Options
Illumination is a critical factor in microscopy, and the BX51 offers a range of options to optimize lighting for various applications:
- 100W halogen bulb for bright, clear transmitted light viewing
- Two neutral density filters (ND6 and ND25) for light attenuation
- Daylight balancer for color correction
- Additional filter slot for customization
Expandable Nosepiece and Stage
The BX51 nosepiece can accommodate up to eight objective lenses, providing researchers with the flexibility to select the ideal magnification for their specific needs. The large, ceramic-coated stage offers protection and durability, although the matte finish can make cleaning oil spills challenging.
Digital Imaging Capabilities
One of the most popular customization options for the BX51 is the ability to add digital cameras for capturing high-quality images. While lower-resolution cameras may yield disappointing results, integrating a high-resolution camera with the BX51's exceptional optics can produce stunning micrographs.

Olympus BX51 Microscope Anatomy and Optical Path
Understanding the internal components and optical path of the BX51 can help users optimize its performance and troubleshoot any issues that may arise. A cutaway diagram of the BX51 reveals the following key components:- Illuminator: Contains the light source (100W halogen bulb) and collector lens to provide bright, even illumination.
- Substage condenser: Focuses light from the illuminator onto the specimen for optimal contrast and resolution.
- Specimen stage: Holds the slide or sample being examined; the BX51 features a large, ceramic-coated stage for durability.
- Objective lenses: The BX51 nosepiece can hold up to eight objectives, typically including UPLANFL 4X, 10X, 20X, 40X, and 100X oil immersion lenses.
- Trinocular head: Allows for simultaneous viewing through the eyepieces and attachment of a digital camera for imaging.
- Eyepieces: The BX51 commonly uses 10x eyepieces for comfortable viewing at various magnifications.
- Fluorescence illuminator (optional): Consists of a mercury lamp housing, power supply, and fluorescence filter turret for fluorescence microscopy applications.
As light passes through the optical train from the illuminator to the eyepieces or camera, it is focused and conditioned to provide the clearest, most detailed view of the specimen possible. The BX51's UIS optics and various contrast methods (e.g., phase contrast, fluorescence) work together to enhance the image quality and reveal subtle details within the sample.
