4Lasers provide mounted achromatic (broadband) half-wave and quarter-wave retardance waveplates for several bands in the wavelength range of 460 nm - 1700 nm. Air-spaced construction enables to use these waveplates for high-power applications. These waveplates are ideal for multiple wavelengths and broadband operation, due to their constant retardance over a particular broad wavelength range.
