|Single color LED used for fluorescence excitation has bandwidth to some
extent, and causes unwanted background glow to be captured along when documenting
gel. Consequently, it is often
difficult to observe the band with regular LED lighting system, especially when Ex/Em wavelengths are too close or fluorescence is too weak. LED505-TR60W (Cyan), LED470-TR60W (Blue) and darkfield type LED470-DF36W (Cyan), LED505-DF36W (Blue) solved this problem with newly developed
compound dichroic filter. With its ability to cut wavelengths at extremely
compound dichroic filter effectively eliminate unwanted background glow.
