Pigtailed Collimators
CFS-T Pigtailed Collimators are designed for OEM applications. These are supplied with a 1-meter fiber pigtail.The input end of the fiber is normally cleaved.
The fiber and an AR-coated, aspheric micro lens are rigidly potted inside the stainless steel Collimator body. In order to ensure optimum collimation, it is essential that the wavelength be specified when ordering. Custom modifications for non-collimated applications or larger-than-standard beam diameters are possible. Please inquire.
Insertion loss is < 0.2 dB. Back reflection (return loss) is > -55 dB* on all SM models. Pigtailed Collimators have a 1-meter fiber pigtail. For other lengths, order as dash-number. For example, for a 3-meter pigtail, order as CFS-T-5-1550-3.
*RL higher for CFS-T-11-λ and CFS-T-18-λ
