OPTICAL COMPONENT ASSEMBLY

摘要

PURPOSE: An optical component assembly is provided, which prevents a damage of the optical component due to a soldering failure and a shield failure generated by a rapid expansion of a solder to be pushed out of a housing. CONSTITUTION: The optical component assembly comprises a housing(470), the first optical component(480), the second optical component(485), an internal pressure control unit formed in the housing and a sealing unit formed in the housing. The first and the second optical component are installed in the housing with a fixed separation each other and have an empty space(486) between them. Diameters of the optical components are smaller than an internal diameter of the housing, and the first gap(G3) is formed between an outer circumference of the first optical component and an inner circumference of the housing, and the second gap(G2) is formed between an outer circumference of the second optical component and the inner circumference of the housing. And a sealing unit(491) is formed in the first and the second gap to prevent the inflow of external moisture into the housing.
