MLL-V-671-SM671 nm red CW laser
671 nmThe MLL-V-671-SM is a 671 nm continuous-wave fiber-coupled laser source. The laser output is coupled into an optical fiber for delivery to the experiment. The fiber core, numerical aperture and connector determine compatibility with the receiving optics. 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.
