BrightLine® Multiphoton LaserMUX™ Beam Combiners

Semrock’s Multiphoton LaserMUX beam combiners enable deeper tissue imaging and improved contrast in multi-color and multi-modal fluorescence microscopy.  The filters set new performance standards by simultaneously achieving high transmission, high reflection, and low GDD over both reflection & transmission, while maintaining minimal wavefront distortion.  Ideal for combining two femtosecond pulsed laser beams, they are perfect for optogenetics and other life science applications.

Combine two or more femtosecond pulsed lasers such as Ti:Sapphire (& OPO coupled), neodymium and ytterbium-doped fiber and glass lasers, and Cr-forsterite lasers.

Minimal pulse dispersion for femtosecond laser applications
     < ± 100 fs² GDD at popular laser wavelengths
     < ± 500 fs² GDD over entire reflection & transmission


Wavefront performance designed for deep tissue & in vivo imaging    
      < 1λ P-V Reflected Wavefront Error (RWE) on 1 mm
      < λ/10 P-V Transmitted Wavefront Error (TWE)

Achieve higher transmission and reflection %, as well as expanded range for reflection & transmission bands by aligning polarization of laser beam with the spectral performance of the filter.
