Abstract: An optical receptacle has a configuration wherein light of a light-emitting element is separated into a coupling light and a monitor light by a coupling lens face portion and a monitor lens face portion of a first lens face. The coupling light is reflected by a first reflective surface and then emitted towards an optical transmission body from a coupling light emission surface. The monitor light is reflected by a second reflective surface and then emitted towards a light-receiving surface from a monitor light emission surface.

Abstract: The optical receptacle of the invention includes plural first optical surfaces allowing light emitted from plural light emitting elements to be incident thereon, plural second optical surfaces emitting the light incident on the first optical surfaces toward plural optical transmission members, and a third optical surface reflecting the light incident on the first optical surfaces toward the second optical surfaces. The distances between the center of the first optical surface and the light-emitting surface of the light emitting element and between the center of the second optical surface and the light-emitting surface of the light emitting element is longer toward the center from both ends of the row. The center-to-center distances of the first optical surfaces and of the second optical surfaces are shorter, respectively, than the distance between optical axes of light emitted from the light emitting elements and the center-to-center distance of light-receiving surfaces of optical transmission members.

Abstract: In an exemplary configuration, a lens array and a light module using the same include a first lens surface 11 and a second lens surface 12 formed into surface shapes such that by expanding the luminous flux diameter of light as the light travels from the first lens surface 11 toward the second lens surface 12, a light spot on the second lens surface 12 is larger in diameter than a light spot on the first lens surface 11, whereby the effects on optical performance by foreign objects and scratches on the lens surface can be mitigated, the criteria for the outward appearance of the lens surface can therefore be mitigated and the yield rate improved, and costs can be reduced.

Abstract: A surface (17d′) facing a photoelectric conversion apparatus is formed on the optical block (3) side, said surface having light from a light emitting element (10) inputted thereto and monitor light outputted therefrom, and a coupling light output surface (12) having coupling light outputted therefrom is formed on the optical housing (4) side, and consequently, the surface (17d′) and the coupling light output surface (12) are simply and highly accurately formed. Then, an optical block (3) and an optical housing (4) are simply and accurately combined by being fitted together by means of fitting sections (21, 24).
