Semrock offers a wide range of dichroic beamsplitters optimized for pulsed lasers used in multiphoton applications. These multiphoton dichroics have low GDD that helps minimize temporal pulse broadening of transmitted laser beams while exhibiting steep edges with very high and flat reflection and transmission bands.

These are ideal solutions for femtosecond pulsed lasers such as Ti:Sapphire (& OPO coupled), neodymium- and ytterbium-doped fiber and glass lasers, enabling deep tissue imaging with improved constrast.
