The perfect dichroic beamsplitters for the most popular lasers used in fluorescence imaging, including all-solid-state lasers for advanced microscopy. All beamsplitters in this category have exceptional reflectance at the key laser wavelengths, and wider reflection bands — into UV for photoactivation and super-resolution techniques. Additionally they feature extended transmission regions — into IR to 1200 or 1600 nm, and anti-reflection (AR) coatings to minimize imaging artifacts resulting from the coherent laser light.
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, and STED.
1λ P-V RWE on 1 mm, optimized for reflecting laser beams up to 10 mm in diameter while minimizing RWE
λ/5 P-V RWE on 3 mm, optimized for reflecting laser beams up to 22.5 mm in diameter while minimizing RWE
