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.
