This tutorial shows how to set up a multi-element objective lens. The chosen lens is the Double Gauss described in 'Modern Lens Design (2nd edition)', by W. Smith, 2005, pg 323. The tutorial demonstrates how to create a geometry sequence using the 'Spherical Lens 3D' part found in the COMSOL part library. Also demonstrated are the use of clear apertures, as well as edge and aperture obstructions. Finally, the results of a grid-based ray trace at a single wavelength and field angle are shown graphically.
