21 September 2007 Alignment and tolerancing of a cardioid condenser
Author Affiliations +
Design details of a cardioid dark field condenser are shown ranging from the theoretical performance of a cardioid to the best-fit spherical surface. The manufacturing tolerances, fabrication techniques and debug methods are discussed for this condenser. The primary tolerances to be achieved are center thickness of the cardioid element and maintenance of its center of curvature relative to the focal plane.
