WebJan 19, 2011 · including film thickness, refractive index, coating homogeneity and reflectivity. The measurement of film thickness using reflected light is a well-established technique1. Such optical techniques for the determination of thin film characteristics rely upon the interaction of the film with light, and can constants. WebThis is important because many lens designs may not have a size available that fit the patient’s frame choice. MBS = (GCD - PD) + ED For example if the frame we choice has a frame PD of 75, the patient’s PD is 65 and the ED is 50 then the MBS would be calculated as MBS = (75-65) + 50 = 10 + 50 = 60 mm Nominal Lens Formula
