定焦光纤准直器经过预对准,用于准直FC/PC、FC/APC或SMA接头光纤的输出光。每个准直器都经过出厂对准,在波长范围从700到2000nm内提供衍射极限性能。虽然这些准直器可在非设计波长处使用,但是由于非球面透镜存在色差,有效焦距会随波长变化而变化,因此它们只有在设计波长处才能提供最佳性能。

These fiber collimation packages are pre-aligned to collimate light from an FC/PC-, FC/APC-, or SMA-terminated fiber. Each collimation package is factory aligned to provide diffraction-limited performance for wavelengths ranging from 700 nm to 2 µm. Although it is possible to use the collimator at detuned wavelengths, they will only perform optimally at the design wavelength due to chromatic aberration, which causes the effective focal length of the aspheric lens to have a wavelength dependence
