Optical thickness

WebVariation of the center thickness of a lens can affect the optical performance because center thickness, along with radius of curvature, determines the optical path length of rays passing through the lens. Typical manufacturing tolerances for center thickness are: +/-0.20 mm for typical quality, +/-0.050 mm for precision quality, and +/-0.010 ... WebOur thickness gauge products conveniently measure thickness with the reliable accuracy and exceptional repeatability that are required for the most demanding applications. These systems employ a proven optical technique that can analyze hard and soft materials without damage or deformation.
