Mode-Conditioned Light Sources
625 nm, Ø105 µm Core
Connecting a Compatible Patch Cable Does Not Disrupt the Flat-Top Profile of the Mode-Conditioned Source
Thorlabs' Mode-Conditioned Light Sources are fiber-coupled LED sources that have an output with a flat-top profile in the far field. Common applications include the testing of multimode fused fiber components as well as verification of modal behavior in fiber-based setups. Standard fiber-coupled LED sources can have a range of output profiles that are usually not uniform and vary from source to source. This can be dependent on emitter orientation, alignment with fiber tip, and connector assembly. These mode-conditioned sources have been engineered to distribute light evenly into all transverse modes, resulting in an equilibrium modal distribution at the output. The front panel includes an adjustment knob to control the power and an output port that accepts 2.2 mm wide-key FC/PC connectors. A DS15 15 V power supply with a location-specific plug is included with each device.
See the tables below for 1 m long patch cables verified to work with each item #. Longer patch cables will not affect the overall output distribution, but will reduce the throughput slightly due to fiber attenuation.
