MDL-XN-39003900 nm infrared CW laser
3900 nmThe MDL-XN-3900 is a 3900 nm continuous-wave laser source. The TTL and analog modulation options control different things: TTL gates the beam on and off, while analog control varies its intensity. Modulation bandwidth sets how quickly the source can follow a changing command.
