Note: This calculator follows the standard sign convention for the optical radius of curvature where if the vertex of a surface lies to the left of the center of curvature the radius of curvature is positive, and if the vertex lies to the right of the center of curvature the radius of curvature is negative. In the figure, R1 is positive and R2 is negative.
Relate optical and mechanical parameters of simple lenses in order to ease integration into application assemblies. Select index from list of EO's own optical substrates to help calculate focal lengths and principal points of any standard lens.
