Regrettably, the discontinuation of several key components has made it impossible to produce the DG-4 and DG-5 wavelength switchers. We highly recommend our new Lambda 721 as a direct replacement for the DG-4. The Lambda 721 offers faster switching, better reliability, higher efficiency, more filter channels, and software compatability with many imaging applications. The Lambda 721 was designed from the ground up as a next generation, ultra high-speed wavelength switcher.
