finesse.tracing.abcd.mirror_refl_t

finesse.tracing.abcd.mirror_refl_t(Rc, nr=1)

Tangential (in plane-of-incidence) reflection from a curved surface. Due to coordinate system change on reflection the sagittal plane is reflected (parity operation) and an additional minus sign is applied.

Parameters

Rcfloat

Radius of curvature of the surface being reflected from. A positive Rc means the surface appears concave to the incident beam.

nrfloat

refractive index of medium in which the reflection occurs
