835 nm BrightLine® multiphoton 3P short-pass super-resolution / TIRF dichroic beamsplitter

Semrock Part Number: FF835-SDi01-t3-25x36

IDEX Part Number: FL-413703  /

Semrock
Innovative short pass dichroic beamsplitter optimized for 3-photon laser excitation in a standard epi-fluorescence microscope configuration with reflected excitation and transmitted emission.

The 2-photon (Red) and 3-photon (Green & Red) excitation regions are ideal for femtosecond pulsed lasers such as Ti:Sapphire, OPO or OPA coupled, and neodymium- and ytterbium-doped lasers, enabling deep tissue imaging with improved contrast. This multiphoton dichroic has low reflected GDD that helps minimize temporal pulse broadening of reflected 1300 nm and 1700 nm laser pulses, and very high and flat reflection and transmission bands.

Semrock's Super-resolution / TIRF dichroics are available in two thicknesses and deliver industry-leading flatness for minimal focus shift and optical wavefront aberrations of the laser beam spot to enable popular imaging and super-resolution techniques such as TIRF, PALM, STORM, structured illumination, STED, and multiphoton imaging.

2.5λ P-V RWE on 1 mm, optimized for reflecting laser beams up to 6 mm in diameter while minimizing RWE
λ/3 P-V RWE on 3 mm, optimized for reflecting laser beams up to 16.7 mm in diameter while minimizing RWE
