Manufactured from low autofluoresence substrates, Newport\'s dichroic laser beam combiners can efficiently combine or separate multiple laser beams at a 45° angle of incidence. An ion-beam sputtered coating is applied to laser grade substrates to provide high reflection (>98%) and transmission (>95%) with low scattering. These laser beam combiners are the perfect choice for multi-laser imaging and analytical instruments. 

For optimal filter performance:
When combining beams, the arrow on the side of the ring should point toward outgoing transmitted & combined laser beam.
When separating beams, the arrow on the side of the ring should point toward incoming combined beam and outgoing reflected beam.
