Semrock Optical Filter: FF409/493/596-Di02  FF409/493/596  Di02
409/493/596 nm BrightLine® triple-edge dichroic beamsplitter
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 and metal halide lamps.
