准直器类型: Aspherical 设计波长: 543nm AR 涂层: One side
Lightpath Technologies生产各种产品,旨在收集来自光纤电缆的光并产生准直光束。Lightpath的连接器准直器组件系列将玻璃模制非球面透镜的卓越性能与光纤连接器接口的轻松组装相结合。LightPath的大光束熔合光纤准直器采用专利光纤熔合技术,使准直器能够在非常高的功率下使用。该准直器采用了Lightpath'的专有透镜技术,在具有成本效益的封装中提供类似非球面的性能。Lightpath'的小型光束准直器采用我们的专利激光聚变技术生产。该工艺将光纤末端直接熔合到透镜的光学中心——消除了光路中的环氧树脂。然后对准直器透镜表面进行激光抛光,使其达到百万分之一英寸的理想形状,从而提供极低的插入损耗。这种高的单件质量转化为更有效的组装过程。

与传统透镜相比,使用菲涅尔透镜的优点是其紧凑的尺寸。常见用途包括高架投影仪、袖珍放大镜和运动探测器。菲涅尔(Fresnel)一词源于奥古斯丁-让·菲涅尔(Augustin-Jean Fresnel),他于1820年首次使用这种设计来建造灯塔透镜。然而,将透镜表面划分为同心环以减少重量和尺寸的想法可以追溯到1748年,由乔治·路易斯·勒克莱尔(Georges-Louis Leclerc)提出。菲涅尔透镜可以由塑料或玻璃制成。也有不同的设计变化,如正菲涅尔透镜,负菲涅尔透镜,柱面菲涅耳透镜,菲涅耳透镜阵列,线性菲涅耳透镜,双凸透镜和菲涅耳棱镜。
