Optimized beamsplitters for the most popular lasers used in fluorescence imaging, including newer all-solid-state lasers for conventional laser based microscopy such as confocal imaging. All beamsplitters in this category have exceptional reflectance at the laser wavelengths, and anti-reflection (AR) coatings to minimize imaging artifacts resulting from the coherent laser light. This dichroic beamsplitter is optimized for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.

Interested in an improved Flatness / RWE version? Consider Semrock's Super-resolution / TIRF dichroics:
1λ P-V RWE on 1mm Di03-R488/561-t1 , optimized for reflecting laser beams up to 10 mm in diameter while minimizing RWE
λ/5 P-V RWE on 3mm Di03-R488/561-t3, optimized for reflecting laser beams up to 22.5 mm in diameter while minimizing RWE
