Olympus U-ECA Magnification Changer

The Olympus U-ECA Simple Magnification Changer is a versatile optical accessory that expands the magnification range of Olympus infinity-corrected microscopes without requiring additional objectives. This intermediate magnification changer mounts in the optical path between the objective and eyepiece, providing two selectable magnification positions: 1× (standard) and 2× (doubled).

By offering instant magnification switching, the U-ECA enables researchers and technicians to quickly zoom in for detailed examination or return to standard magnification for broader field coverage — all without rotating the objective nosepiece or interrupting the observation workflow. This is particularly valuable when working with specimens that require frequent transitions between overview and detail imaging, such as tissue sections, cell cultures, or materials samples.

The U-ECA is engineered for compatibility with Olympus CX, BX, IX, MX, and GX series microscopes, integrating seamlessly into the infinity-corrected optical system. The precision-designed optics maintain excellent image quality in both magnification positions, preserving sharpness, contrast, and chromatic correction across the field of view.

The simple two-position design features a smooth, positive-detent mechanism that ensures accurate positioning and prevents drift during use. This makes the U-ECA an ideal solution for laboratories seeking to maximize imaging flexibility without investing in additional objectives or compromising optical performance.
