What Does a Vertical Light Path System Measure? – Omega Metrology

A Vertical Light Path Vision Measurement System is a high-precision, non-contact optical measuring tool used to capture and evaluate the geometrical dimensions of small and complex components. At Omega Metrology, these systems are used to deliver accurate and repeatable results in dimensional inspection for industries such as electronics, automotive, aerospace, and medical devices.

The term "vertical light path" refers to the orientation of the optical axis – where the lens and camera system look vertically downward onto the object being measured. This configuration ensures a stable and controlled optical environment for capturing high-resolution images of a part's surface.

Primarily, a vertical light path system measures 2D and limited 3D features such as:

  • Length

  • Width

  • Height (Z-axis with optional probes or lasers)

  • Angles

  • Radii

  • Diameters

  • Hole positioning

  • Flatness and edge profiles

Omega Metrology’s systems combine high-quality telecentric lenses, precision granite stages, and advanced image processing software to deliver micron-level accuracy. The system uses LED-based ring lights and backlighting to enhance feature detection, edge contrast, and contour analysis.

These systems are ideal for inspecting parts that require non-contact evaluation, where touch probes could damage delicate surfaces. Common components include PCB boards, machined parts, plastic molds, watch components, and surgical tools.

In summary, the Vertical Light Path Vision Measurement System at Omega Metrology is designed to measure critical dimensions, tolerances, and shapes with high repeatability and efficiency. It supports quality assurance, reverse engineering, and production control by providing fast, accurate, and automated inspection without physical contact with the part.
