Semrock LaserMUX Laser Beam Combiners

LaserMUX filters from Semrock are designed to efficiently combine or separate multiple laser beams at a 45° angle of incidence. These dichroic laser beam combiners are optimised to multiplex (MUX) popular laser lines, and can also be used in reverse to demultiplex (DEMUX).

The ultralow-autofluorescence filters are ideally suited for OEM multi-laser fluorescence imaging and measurement applications including laser microscopy and flow cytometry, as well as for myriad end-user applications in a laboratory environment.

With high reflection and transmission performance at popular laser lines, these filters allow combining multiple different laser beams with exceptionally low loss. LaserMUX filters are hard-coated and come in an industry-standard 25mm diameter x 3.5mm black-anodised aluminium ring with a generous 22mm clear aperture.

As the industry’s best for high-performance optical filters, Semrock products from IDEX Health & Science deliver the stability required for life science, analytical, and medical diagnostic instrumentation. By utilising proprietary hard-sputtered coatings, our filters eliminate environmental degradation and drift—a level of reliability backed by our 10-year warranty. We ensure faster measurements and minimal downtime by prioritising steep edges and deep blocking to maximise your signal-to-noise ratios. From standard components to custom solutions, Semrock filters provide the superior stability and spectral precision necessary to optimise the most demanding optical systems.
