850 nm BrightLine® Multiphoton LaserMUX™ Beam Combiner

Semrock Part Number: FF850-Di01-t1-25x36

IDEX Part Number: FL-006983  /

Semrock

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.

< 1λ P-V RWE on 1 mm, optimized for reflecting laser beams up to 10 mm in diameter while minimizing RWE
< λ/10 P-V Transmitted Wavefront Error
