finesse.tracing.abcd.beamsplitter_trans¶
- finesse.tracing.abcd.beamsplitter_trans(Rc, alpha, nr1=1, nr2=1, direction='x')[source]¶
 Transmission through a curved surface at an angle of incidence.
- Parameters:
 - Rcfloat
 Radius of curvature of the surface being reflected from. A positive Rc means the surface appears concave to the incident beam.
- alphafloat
 Angle of incidence in degrees
- nr1float
 refractive index of medium the beam starts in
- nr2float
 refractive index of medium the beam ends up in
- directionstr
 Which plane this reflection occurs in, either x or y.
