670 nm edge BrightLine® multiphoton short-pass dichroic beamsplitter

Semrock Logo

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 reflected laser beams while exhibiting steep edges with very high and flat reflection and transmission bands. This laser dichroic beamsplitter is optimized for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.

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 contrast.

Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spectral plot data, please see here for more information.
