TECHSPEC® 近红外(NIR)消色差透镜旨在为 750 至 1100nm 波长的多色光提供尽可能小的光斑尺寸。例如，在使用多色光时，通过使用我们的近红外双色镜片而不是为可见光设计的标准双胶合镜片，RMS光斑直径可从 43μm 减小到 22.5μm。聚焦单色光源时，光斑尺寸会更小。TECHSPEC®近红外(NIR)消色差透镜还能减少球差，在与波长最高达 2μm 的单色光源一起使用时，表现更为出色。这些双胶合透镜的典型应用包括近红外成像镜头、近红外激光器的聚焦和扩展，以及光纤和近红外 LED 的聚焦/准直透镜。
旨在为近红外波长（750-1100 纳米）提供更高的分辨率和更小的光斑尺寸
降低单色光源（2μm 以下）的球面像差
宽带 AR 镀膜在 750-1550nm 波长范围内的反射率小于 1%
