In response to customer demands for isolators with increasingly broad tuning ranges, Leysop has introduced a new design of isolator based on the FOI5/57 design but using a slightly longer than normal TGG rod and greater strength magnet assembly to increase the maximum wavelength of operation. More importantly, it provides a new, more convenient wavelength tuning assembly.
The photograph at right shows the device at the two extremes of the tuning range. It also shows clearly the helicoidal tuning mechanism which produces pure translation of the TGG rod into the magnet assembly, without rotation of either the rod or alteration of the relative orientation of the polarizers. The tuning mechanism is extremely smooth and allows very precise adjustment of the tuning to maximize isolation over the extraordinarily wide wavelength range of 650-1,100 nm, all in one device.
