MLL-U-671-SM671 nm red CW laser
671 nmThe MLL-U-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. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
