Optical module device and optical assembly

The invention provides an optical module device and an optical assembly. The optical module device includes: a first collimator lens; a second collimator lens; a first filter; a second filter; and a prism. The relative positions and optical performance of the five parts enable light splitting and light convergence to be realized at low cost, and the TO package can be installed perpendicular to the collimation direction of the collimator lens, so that additional planning of a shell of the optical module device or additional planning of an assembly mode or an assembly component of the TO package is not needed, and the assembling difficulty when the optical module device is matched with the TO packaging piece is effectively reduced. 本发明提供一种光模块器件和光学组件。所述光模块器件包括：第一准直器透镜；第二准直器透镜；第一滤波片；第二滤波片；棱镜。五者的相对位置以及光学性能使得低成本的实现分光和光线汇聚，并且让所述TO封装件可以垂直于所述准直器透镜的准直方向安装，无需对光模块器件的外壳进行额外的规划，或者对TO封装件的装配方式或装配组件进行额外的规划，有效的降低了光模块器件与TO封装件配合使用时的装配难度。
