PGL-H1-594594 nm orange CW laser

594 nm

The PGL-H1-594 is a 594 nm continuous-wave laser module. The optical head packages the light source for integration into an instrument. Its specified driver and cooling arrangement determine how the module is powered and stabilized. Waste heat is removed through the specified mounting or cooling interface. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
