Emitter TO-CAN package capable of emitting parallel light

The invention discloses an emitter TO-CAN package capable of emitting parallel light. The emitter TO-CAN package comprises a TO base, a laser assembly and a collimating lens assembly. The laser assembly is fixed on the TO base; the collimating lens assembly is coupled to the top of a light-emitting optical axis of the laser assembly. According to the emitter TO-CAN package capable of emitting parallel light, the laser chip is fixed on the chip carrier and is connected with an external circuit through the bound gold wire, and the collimating lens assembly at the top of the laser chip is coupled and fixed with the laser chip, so that the emitted light is parallel light beams; the problem of light splitting and parallel optical coupling of an optical device is solved, the requirement for miniaturized packaging of the optical device is met, the TO-CAN emission cost rate is greatly reduced, and the product has great market popularization and application value. 本发明公开了一种平行光出光的发射器TO-CAN封装，包括：TO底座、激光器组件和准直透镜组件；激光器组件固定
