The Keyence VH-Z500T is an ultra-high magnification zoom lens designed for advanced digital microscopy applications. With its capability to achieve magnification levels from 500× to an extraordinary 5000×, the VH-Z500T provides researchers, engineers, and quality control professionals with the ability to observe surfaces and structures at scales far beyond conventional optical limits.

At 500× magnification, the lens delivers a horizontal field of view (FOV) of 610 µm, ideal for scanning broader regions of interest while still revealing intricate details. As magnification increases, the FOV narrows progressively: at 2000×, the horizontal FOV is just 152 µm, and at the maximum 5000× magnification, the horizontal FOV tightens to an incredibly fine 61 µm, with a corresponding diagonal FOV of 76 µm. This allows for detailed analysis of microscopic structures such as surface roughness, micro-cracks, grain boundaries, and fine defects that are invisible under lower magnification systems.

The lens maintains a working distance of 4.4 mm (0.17″), a critical factor in supporting ultra-high magnification imaging. This short but stable distance ensures that the sample remains within optimal focus, delivering the sharpness and resolution required for nanometre-level observation. The precise working distance also allows for enhanced stability, which is essential when working at extremely high magnifications where even the slightest vibration can affect image quality.

Engineered with premium optical design, the VH-Z500T ensures crystal-clear imaging across its entire magnification range. By minimising distortion and maximising resolution, the lens provides accurate, reliable results essential for industries and research fields that demand uncompromising precision. This clarity is especially important in applications where measurements and visual analysis must be highly repeatable and dependable.

The VH-Z500T is invaluable in industries such as semiconductor manufacturing, materials science, nanotechnology, and medical research. In semiconductor inspection, it enables the detection of micro-scale defects in wafers and circuits. In materials science, it supports detailed evaluation of microstructures, coatings, and surface treatments. Medical and life sciences applications benefit from its ability to visualise tissue structures, cell morphology, and biomaterial surfaces at unmatched magnification.

In addition to research, the VH-Z500T also supports practical quality control and failure analysis, helping manufacturers maintain the highest standards of precision and reliability. Its ability to capture minute variations ensures that defects are identified early, preventing costly errors and enhancing overall product quality.

In summary, the Keyence VH-Z500T is an advanced zoom lens designed for ultra-high magnification microscopy. With a range of 500× to 5000× magnification, fine-tuned FOV from 762 µm down to 76 µm, a stable 4.4 mm working distance, and superior optical clarity, it offers a powerful solution for cutting-edge inspection and research. This lens empowers users to explore the microscopic world in unprecedented detail, supporting innovation, precision, and quality assurance across a wide spectrum of industries.
