Class BeamSplitter

source code

Beamsplitter class.

This class represents beam splitters composed of two faces (HR, AR)
and with a wedge angle. These are the objects with which the beams will
interact during the ray tracing. Please see the documentation for details
on the geometric construction of these optics.

Beam Splitters behave exactly like mirrors, except that:
    * The default values for transmittances and reflectivities are different
    * Beam splitters never increase the order upon interaction of beams.

Actions:
    * T on HR: 0
    * R on HR: 0
    * T on AR: 0
    * R on AR: 0

**Note**: the curvature of any surface is positive for a concave surface
(coating inside the sphere).
Thus kurv*HRNorm/|kurv| always points to the center
of the sphere of the surface, as is the convention for the lineSurfInter of
geometry module. Same for AR.
