PGL-F-405405 nm violet CW laser

405 nm

The PGL-F-405 is a 405 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.
