摘要	There is provided an optical head comprising a mount material (30) for fixing an optical element (10) and a mount material (40) for fixing an optical fiber array (20) to which an optical fiber (21) is connected, the optical fiber (21) being optically connected to the optical element (10), wherein an angle formed between the light emission receiving face of the optical element (10) and the end face of the optical fiber (21) is in the range 1 to 8 degrees. In comparison with a conventional optical head in which alignment using inspection light is performed, and a light emission receiving face and an end face of an optical fiber are substantially parallel to each other, noise produced by reflection light deriving from an end face of the optical fiber opposed to the light receiving face or light emitting element is reduced.
其他摘要	提供一种光学头，包括用于固定光学元件（10）的安装材料（30）和用于固定光纤（21）所连接的光纤阵列（20）的安装材料（40），光学元件光纤（21）光学连接到光学元件（10），其中光学元件（10）的光发射接收面和光纤（21）的端面之间形成的角度在1到8的范围内度。与使用检查光进行对准的传统光学头相比，并且光纤的发光接收面和端面基本上彼此平行，由光学的端面产生的反射光产生的噪声。与光接收面或发光元件相对的光纤减少。
主权项	An optical head comprising a mount for fixing an optical element and a mount for fixing an optical fiber array, the optical fiber being optically connected to the optical element, wherein the angle formed between a light emission or receiving face of the optical element and an end face of the optical fiber is in the range 1 to 8 degrees.
