Abstract
An oven for cooking with light having wavelengths in the visible, near visible, and infra-red spectral ranges uses one or more quartz halogen tungsten lamps or quartz arc bulbs positioned above and below the food item. Uniform cooking of the food item is achieved by positioning the lamps asymmetrically with respect to the midline of the oven and by rotating the food item on a rack during the cooking cycle.
