Optical component using optical transmission element joining metal holder |
摘要 |
<p>An optical component comprises an optical transmission element (e.g., an optical lens) whose circumferential wall partially joins a metal holder via a joining material (e.g., a low melting point glass), wherein stress is normally applied to the optical transmission element in a compression direction when joining the metal holder. The optical transmission element is inserted into a through hole of the metal holder, and the joining material is kept in a bank actualized by a tapered portion formed in proximity to one end of the through hole of the metal holder. This prevents tensile stress from being applied to the optical transmission element; thus, it is possible to avoid the occurrence of cracks and separations in the optical transmission element; and it is possible to avoid the occurrence of errors in optical characteristics, regardless of variations of the environmental temperature, so that, the optical component is improved in reliability.</p> |
