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
