Multi-edge dichroics have two or more transitions from high reflectance to high transmission. Semrock offers a wide range of dichroic beamsplitters that exhibit steep edges with very high reflection and transmission bands. This standard epi-fluorescence dichroic beamsplitter is optimized only for broadband light sources such as LEDs or similar light engines.
BrightLine dichroic beamsplitter for CFP/YFP imaging channels optimized for Lumencor CELESTA light engine® utilizing 445 nm & 518 nm wavelengths.
