Description Sets the bending parameter for a specific singlet lens.
Syntax SetLensBending n, bend
Parameters n As Long Node number of the singlet.
bend As Double The new bending parameter for the singlet.
Remarks This subroutine sets the bending parameter for a specific singlet lens. The bending factor specifies the shape of a lens. It can take on any value with common values being +1 (convex-plano, i.e. the back surf is flat), 0 (front and back surfs have equal and opposite, i.e. equi-convex), -1 (plano-convex, i.e. the front surface is flat). Values outside the range of -1 to +1 are uncommon. If there is a problem the function sets an error and returns without modifying the singlet.
