New Options for Easy Control of the Sutter Lambda VF-1 and VF-5 Variable Filter Systems

The Lambda VF-1 and VF-5 allow easy selection of any available wavelength through keypad control or through the computer interfaces (USB and RS232). This technical note details how the control firmware has been extended to offer two additional control modes that allow selection of new wavelengths without having to modify existing software. It describes the ‘triggered mode’, filter selection commands and support for the VF-1 and VF-5.
