The "Optical Designer" package is intended for simulating optical systems by ray tracing.
Calculation of optical systems in the forward trace of the rays and allowance for scattering by method of reverse tracing * on the reflecting surfaces by specifying the scattering indicatrix.
Calculation of the scattering spot by method of tracing straight and diffusely reflected rays from optical elements and structural elements.
Estimation of the level of extra-field illumination in the form of the angular dependence of the illumination intensity of the focal plane by radiation coming at a certain angle with respect to the illumination from axial illumination.
