D2-130 Isolator Module

The isolator module contains a 30 dB isolator and 1/2-wave plate in a rugged and compact package. The beam height matches other D2-series modules. The D2-130 can be used whenever extra isolation is desired, such as added isolation prior to fiber coupling.

• >30 dB isolation
• Half-wave plate
• Compact

D2-120 Fibre Coupling Module

The D2-120 is designed to facilitate coupling of a laser beam into either a single or multimode optical fiber. This module incorporates an optional 35 dB optical isolator, prior to the fiber facet, to reduce optical feedback. An FC fiber receptacle is provided with an aspheric AR-coated condensing lens and 6 degrees of freedom for alignment optimization: 3 linear (x, y, z), 2 angular (azimuth, elevation), and 1 rotational (for PM fibers). The incoming beam height matches all D2 series lasers and optical modules. Compatible with a FC-APC and FC-PC fiber connectors.

• Optimized for use with D2 optical modules
• 6 degrees of freedom for alignment
• Optional 35 dB isolator
