Abstract
In practical microcircuitry a two-dimensional source array is necessary to cater for various types and directional orientation of optical features at the image plane. Configurations successfully applied are the annulus and a distribution of sources at the points of a hexagon and an octagon. In each case a single concentrated mercury arc lamp is used as prime source and effectively multiplied or extended by optical means.
