Compact, rugged and highly efficient opto-mechanical unit with dichroic beam combining plate
This fiber-coupled Beam Combiner 2 ⇾ 1 is a compact opto-mechanical unit that combines 2 fiber-coupled sources with different wavelength or wavelength ranges into 1 output fiber cable with high efficiency.
Please note, that this configuration can be used when the difference in wavelength is > 10 nm.
In case of a smaller difference in wavelength (< 10 nm) the configuration 48-MCS-028 is to be preferred.
Optical Setup
The input ports are each fiber-coupled to PM fiber cables.
The radiation is superimposed by means of a dichroic beam splitter.
A polarizer increases the polarization extinction ratio in the common output port.
Fiber Couplers
A fundamental component of a fiber-coupled Beam Splitter are the Laser Beam Couplers, which are the inputs into the opto-mechanical unit collimating the input radiation and, finally, couples the radiation back into the common polarization-maintaining fiber cable. The stability of the total Beam Splitter is determined by the stability of the laser beam coupler.
Dichroic Beam Combiner 2 ⇾ 1, PM, 48-MCS-043
for collimating radiation exiting an optical fiber or as an incoupler
for coupling into single-mode and polarization-maintaining fiber cables
