WebIrregularity, a type of surface accuracy specification, describes how the shape of a surface deviates from the shape of a reference surface. It is obtained from the same measurement as power. Regularity refers to the sphericity of the circular fringes that are formed from the comparison of the test surface to the reference surface. WebSurface Irregularity Surface accuracy is the measurement of the deviation between the actual shape and its intended shape of an optical surface. It is important to specify the expected surface accuracy to prevent extra …

WebThe impact of surface irregularity on Strehl ratio is also dependent on the f/# of the lens. As a general rule, faster aspheres, or aspheres with smaller f/#’s, have greater sensitivity to surface irregularity’s impact on Strehl ratio. For example, Figure 4 compares an f/2 lens to an f/0.75 lens (both with 25mm diameter), and more Strehl ... raymarine 12 axiom proWebAstigmatism occurs when the cornea has an irregular shape.
