General features and applications

SimCa performs cavity ABCD simulation considering TEM00 mode and gaussian optical systems. Three calculation modes are used: linear, ring cavities, single-pass propagation through an optical system. Astigmatism calculation after component tilt (tangential and sagittal beams are considered) is made. SimCa can also performs parametric analysis.
