Abstract: A recording medium stores a lens design program for causing a computer to execute a process including: obtaining a curvature and a first conic with respect to two lens surfaces in which light beams inputted to the optical member become parallel light beams when the optical member is in a first medium; obtaining, based on the obtained curvature, a distance between the two lens surfaces and a second conic that cause the light beams inputted to the optical member to focus at a center between the two lens surfaces when the optical member is in a second medium; and obtaining combinations of optical coupling efficiency in the first medium and the second medium in a case where the optical member based on the obtained curvature and the obtained distance is set between a light emitter of light beams and a light receiver.

Abstract: A search condition specifying unit specifies a search condition item, and specifies a re-search condition item which is desired to be re-searched based on the search result according to the search specified condition. A search processing unit extracts an item value corresponding to the re-search condition item from the search result of the database according to the search condition item, and repeats search of a database wherein the item value serves as the search condition item until no item value is extracted. A search result display unit displays the search result according to the search processing unit in a list.
