Quality Vision International


All QVI illuminators are designed in concert with the optical systems to ensure uniform, bright light throughout the field of view, and over the entire Z-axis range.

Profile illumination (back light) is matched to the f-number of the receiving lens to ensure accurate image formation and uniform brightness across the field.

Through-the-lens square-on surface light is built into all QVI optical systems to enable measurement inside blind holes and cavities the oblique light cannot reach.

Oblique illumination is essential for measurement of surface features that are angled with respect to a part's surface. Ring light designs enable control of the intensity, direction, color and incidence angle of the illumination. QVI offers a range of patented illuminators matched to our exclusive lens systems.
