Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Dual Wavelength Waveplates
Dual wavelength waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths, it's particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength.
