== Common decomposition ==
There exist infinite ways to decompose a ray transfer matrix <math> \mathbf{T} = \begin{bmatrix} A & B \\ C & D \end{bmatrix} </math> into a concatenation of multiple transfer matrices. For example in the special case when <math>n_1 = n_2</math>:
# <math> \begin{bmatrix} A & B \\ C & D \end{bmatrix}
