Zero Phase Shift Mirror, Water-Cooled Copper, 70 mm Diameter, 25 mm Edge, Finn Power

The 630496-117 zero phase shift beam delivery mirror is 2.756 in. (70 mm) diameter with a 25 mm edge thickness, and is Finn Power OEM compatible. These water-cooled copper mirrors reflect the laser beam by an angle of 90º. corresponding to an angle of incidence of 45º. Reflectance of these mirrors is as high as possible in order to minimize losses of laser power. In addition, phase shift between the s- and p-polarized components of the reflected beam is as low as possible in order to avoid disturbing the polarization of the laser beam.
