PGL-F-940940 nm near-infrared CW laser

940 nm

The PGL-F-940 is a 940 nm continuous-wave laser source. Continuous-wave operation provides a sustained beam for experiments that need steady illumination. PC control allows the operating state to be set from software, so illumination can be coordinated with the experiment.
